50 miles per hour  is the rate (speed) of the wind.

Step-by-step explanation:

Let consider the variable ‘x’ for speed of wind.  

Below we write two values of the speed of the airplane in the air in terms of ‘x’:

1. Subtract wind speed from airplane speed: 250 - x.

2. Add wind speed to the airplane speed against the wind: 150 + x.

And now, set these above two expressions equal to each other to find x (wind speed),

                                      250 – x = 150 + x

                                      2x = 100

                                     x = 50 miles per hour

Answer:

$176.40

Step-by-step explanation:

Lets assume the order of events to be:

20 dollars discount first,

2% coupon discount, next

So, original cost is 200

Discount of 20 dollars, means that it now costs:

200 - 20 = $180

Now, we have a 2% discount coupon on it. We have to find 2% of 180 and subtract that from 180.

Note: 2% is 2/100 = 0.02

So,

180 * 0.02 = 3.6

So, final price would be:  180 - 3.6 = $176.40

Mark paid $176.40 for the shoes

Answer:

Step-by-step explanation:

 13x+2y=1

+ 5x-2y=-19

-------------------

18x=18

x=1

5x1-2y=-19

5-2y=-19

-2y=-19-5

-2y=14

-y=7

y=-7

x=1

y=-7

To solve the system, eliminate variables, find [tex]\( x = -1 \)[/tex], then substitute into an equation to get [tex]\( y = 7 \)[/tex].

To solve the system of equations [tex]\(13x + 2y = 1\)[/tex] and [tex]\(5x - 2y = -19\)[/tex], you can use the method of elimination.

First, let's eliminate one of the variables. We can eliminate [tex]\(y\)[/tex] by adding the two equations together:

[tex]\[ (13x + 2y) + (5x - 2y) = 1 + (-19) \][/tex]

This simplifies to:

[tex]\[ 13x + 5x = -18 \][/tex]

[tex]\[ 18x = -18 \][/tex]

Now, divide both sides by 18:

[tex]\[ x = \frac{-18}{18} \][/tex]

[tex]\[ x = -1 \][/tex]

Now that we have found [tex]\(x\)[/tex], we can substitute it into one of the original equations to find [tex]\(y\)[/tex]. Let's use the first equation:

[tex]\[ 13(-1) + 2y = 1 \][/tex]

[tex]\[ -13 + 2y = 1 \][/tex]

Add 13 to both sides:

[tex]\[ 2y = 1 + 13 \][/tex]

[tex]\[ 2y = 14 \][/tex]

Divide both sides by 2:

[tex]\[ y = \frac{14}{2} \][/tex]

[tex]\[ y = 7 \][/tex]

So, the solution to the system of equations is [tex]\(x = -1\)[/tex] and [tex]\(y = 7\)[/tex].

Answer:

Step-by-step explanation:

(A) Given

4(2x - 3) = 4 ( divide both sides by 4 )

2x - 3 = 1 ( add 3 to both sides )

2x = 4 ( divide both sides by 2 )

x = 2

(B)

As a check substitute x = 2 into the left side of the equation and if equal to the right side then it is the solution.

4(2(2) - 3) = 4(4 - 3) = 4(1) = 4 = right side

Hence x = 2 is the solution

Answer:

The solution of the given equation is x = 2.

Step-by-step explanation:

The given linear equation is,

[tex]4(2x-3)=4[/tex]

At first, we will eliminate '4' from the LHS by dividing both sides i.e., LHS and RHS by 4 because '4' is present in multiplication with the term containing unknown in LHS.

So, dividing both sides by '4', we get

[tex]\frac{4(2x-3)}{4} = \frac{4}{4}[/tex]

[tex]\implies 2x - 3 = 1[/tex]

Our next step will be to eliminate '3' from the LHS that is being subtracted from the term containg unknown variable. For this, we will add '3' on both sides of the above obtained equation.

So, adding '3' on both sides, we get

[tex]2x - 3 + 3 = 1 + 3[/tex]

[tex]\implies 2x = 4[/tex]

Now, we will eliminate '2' from the LHS that is in multiplication with the unknown variable 'x'.

For this, we will divide both sides of the above obtained equation by '2'.

So, dividing both sides by '2', we get

[tex]\frac{2x}{2}=\frac{4}{2}[/tex]

[tex]\implies x = 2[/tex]

CHECKING :

For this, we will substitute x = 2 in the LHS of the given equation and then check whether it is equal to RHS or not.

LHS = 4(2x - 3)

= 4(2 × 2 - 3)

= 4(4 - 3)

= 4 × 1

= 4

= RHS

So, the solution of the given equation is x = 2.

Answer:

Probability that a student chosen randomly from the class plays basketball or baseball is  [tex]\frac{23}{30}[/tex] or 0.76

Step-by-step explanation:

Given:

Total number of students in the class = 30

Number of students who plays basket ball = 19

Number of students who plays base ball = 12

Number of students who plays base both the games = 8

To find:

Probability that a student chosen randomly from the class plays basketball or baseball=?

Solution:

[tex]P(A \cup B)=P(A)+P(B)-P(A \cap B)[/tex]---------------(1)

where

P(A) = Probability of choosing  a student playing basket ball

P(B) =  Probability of choosing  a student playing base ball

P(A \cap B) =  Probability of choosing  a student playing both the games

Finding  P(A)

P(A) = [tex]\frac{\text { Number of students playing basket ball }}{\text{Total number of students}}[/tex]

P(A) = [tex]\frac{19}{30}[/tex]--------------------------(2)

Finding  P(B)

P(B) = [tex]\frac{\text { Number of students playing baseball }}{\text{Total number of students}}[/tex]

P(B) = [tex]\frac{12}{30}[/tex]---------------------------(3)

Finding [tex]P(A \cap B)[/tex]

P(A) = [tex]\frac{\text { Number of students playing both games }}{\text{Total number of students}}[/tex]

P(A) = [tex]\frac{8}{30}[/tex]-----------------------------(4)

Now substituting (2), (3) , (4) in (1), we get

[tex]P(A \cup B)= \frac{19}{30} + \frac{12}{30} -\frac{8}{30} [/tex]

[tex]P(A \cup B)= \frac{31}{30} -\frac{8}{30} [/tex]

[tex]P(A \cup B)= \frac{23}{30}[/tex]

Answer: 37 1/3

Step-by-step explanation:

14/1÷3/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

14/1 × 8/3=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

14×8/1×3 = 112/3

This fraction cannot be reduced.

The fraction

112/3

is the same as

112÷3

Convert to a mixed number using

long division so

112/3=37 1/3

Therefore:

14/1 ÷ 3/8=37 1/3

Answer:

x=4

Step-by-step explanation:

Missing picture is attached.

As we can see in the picture drawn, there are two cord insecting outside the circle.

∴ we will use Intersecting secant theorem.

When two secant lines intersect each other outside a circle then the product of the length of the chord and the length of the part outside the circle are equal.  

Now, using the value in theoram as given in the picture.

⇒[tex]x\times 6= 3\times 8[/tex]

Dividing both side by 6

⇒ [tex]x= \frac{3\times 8}{6}[/tex]

∴x= 4

Answer:

x = 1

Step-by-step explanation:

Given

- | x + 2 | + 1 = 4x - 6 ( subtract 1 from both sides )

- | x + 2 | = 4x - 7 ( multiply both sides by - 1 )

| x + 2 | = - 4x + 7

The absolute value always returns a positive value, but the expression inside can be positive or negative, thus

x + 2 = - 4x + 7 ( add 4x to both sides )

5x + 2 = 7 ( subtract 2 from both sides )

5x = 5 ( divide both sides by 5 )

x = 1

OR

- (x + 2) = - 4x + 7, that is

- x - 2 = - 4x + 7 ( add 4x to both sides )

3x - 2 = 7 ( add 2 to both sides )

3x = 9 ( divide both sides by 3 )

x = 3

As a check substitute these values into both sides of the equation and if both sides are equal then they are the solutions.

x = 1 : - |1 + 2| + 1 = - | 3 | + 1 = - 3 + 1 = - 2

right side = 4(1) - 6 = 4 - 6 = - 2 ← True

x = 3 : - |3 + 2| + 1 = - |5| + 1 = - 5 + 1 = - 4

right side = 4(3) - 6 = 12 - 6 = 6 ← False

Thus x = 3 is an extraneous solution and

x = 1 is the solution

Final answer:

Greg's unit rate is  [tex]1\frac{5}{7}[/tex]  walls per hour, which is found by dividing 1/7 of a wall by 1/12 of an hour. The correct answer is option C: [tex]1\frac{5}{7}[/tex].

Explanation:

If Greg can build 1/7 of a brick wall in 1/12 of an hour, we want to find his unit rate, which is the amount of wall he can build per hour. To find Greg's unit rate, we divide the fraction of the wall built by the fraction of the hour spent building it. This calculation gives us:

Unit rate = (1/7) ÷ (1/12) = (1×12)/(7×1) = 12/7 = [tex]1\frac{5}{7}[/tex] walls per hour.

Therefore, the correct option is C: [tex]1\frac{5}{7}[/tex].

Answer:

The value of x is 17°.

Step-by-step explanation:

The two exterior angles on the same side of the transversal are always supplementary.

Therefore, if the measure of two exterior angles on the same side of the transversal are 3x and 7x+10, then we can write  

3x + (7x + 10) = 180°

⇒ 10x = 180° - 10° = 170°

⇒ x = 17°  

Therefore, the value of x is 17°. (Answer)

Answer:

False

Step-by-step explanation:

Answer:

The value of x is 2[tex]\sqrt{29}[/tex] .

Step-by-step explanation:

Given as :

The area of Trapezoid = x² unit²

The measure of base 1 = [tex]b_1[/tex] = - 19 unit

The measure of base 2 = [tex]b_2[/tex] = 10 unit

The height of the mid segment = 8 unit

Now, From the Area of Trapezoid

i.e Area = [tex]\dfrac{1}{2}[/tex] × (sum of opposite base) × height

Or, x² = [tex]\dfrac{1}{2}[/tex] × (19 + 10) × 8

Or,  x² = [tex]\dfrac{8}{2}[/tex] × (29)

Or, x² = 4 × (29)

Or,  x² = 116

∴ x = [tex]\sqrt{116}[/tex]

I.e x = 2[tex]\sqrt{29}[/tex]

Hence, The value of x is 2[tex]\sqrt{29}[/tex] . Answer

Final answer:

Using the properties of a trapezoid's midsegment being the average length of the bases, the equation (10 + (x² - 19))/2 = 8 was solved to find that x equals 5.

Explanation:

The question revolves around the properties of a trapezoid and its midsegment. In a trapezoid, the midsegment (also called the median) is the segment that joins the midpoints of the non-parallel sides and is parallel to both bases.

The length of the midsegment is the average of the length of the two bases, which can be expressed as (base1 + base2) / 2.

Given that the midsegment is 8 units long, and one base is given as 10 units, let the other base be expressed as x² − 19 units. The formula for the midsegment becomes:

(10 + (x² − 19))/2 = 8

Now we solve for x:

10 + x² − 19 = 16

x² − 9 = 16

x² = 25

x = ± 5

Since the measure of a base cannot be negative, the positive root is the realistic solution:

x = 5
