Answer:
The value of x is -0.5.
Step-by-step explanation:
The given equation is
[tex]-2(5x-6)+6x=4(x+4)[/tex]
Use distributive property to solve the above equation.
[tex]-2(5x)-2(-6)+6x=4(x)+4(4)[/tex]
[tex]-10x+12+6x=4x+16[/tex]
[tex]-4x+12=4x+16[/tex]
Add 4x both sides.
[tex]12=8x+16[/tex]
Subtract 16 from both sides.
[tex]-4=8x[/tex]
Divide both sides by 8.
[tex]\frac{-4}{8}=\frac{8x}{8}[/tex]
[tex]-0.5=x[/tex]
Therefore value of x is -0.5.

Answer: x = 0
Step-by-step explanation:
The first step would be to convert everything to one form. I'll do the fractions, since 1/3 is hard to represent in decimal.
3 1/4 + 1/2x + 1 1/3 + 5/6x = 5 11/12
Now, the fractions will be converted via GCF. 12 is easily divisible by 4, 2, 3 and 6, so that I'll be the denominator used.
3 1/4 -> 3 3/12
1/2x -> 6/12x
1 1/3 -> 1 4/12
5/6x -> 10/12x
5 11/12 will stay the same.
The new equation is:
3 3/12 + 6/12x + 1 4/12 + 10/12x = 5 11/12
Combine like terms:
4 7/12 + 1 4/12x = 5 11/12
Subtract 4 7/12 from both sides
1 4/12x = 1 4/12
Divide both sides by 1 4/12x

9m-4=-3m+5+12m how do you solve this equation
Answers
Answer:
Step-by-step explanation:
9m-4 = -3m + 5 + 12m
-9m -9m
-4= -3m + 5 + 12m - 9m
-5 -5
-9 = m
i believe
To solve the equation, simplify both sides and combine like terms. Subtract 9m from both sides to isolate the variable. There is no solution to this equation.
Explanation:To solve the equation 9m-4=-3m+5+12m, we need to simplify both sides and combine like terms.
Starting with the left side, we have 9m-4. On the right side, we have -3m+5+12m. Combining like terms on both sides, we get 9m-4=9m+5. We can then subtract 9m from both sides to isolate the variable, giving us -4=5.
Since -4 is not equal to 5, there is no solution to this equation.

--------------- * ------------- * ---------------
1 kg 14 lbs
All the units cancel except stone

Answer:
42 kilograms is equal to 6.6 stones.
Step-by-step explanation:
Using the given conversion factors:
1 kilogram = 2.2 pounds
1 stone = 14 pounds
To Find: 42 kilograms into stones = ? stones
Solution:
42 kilograms = [tex]42\times 2.2 pounds=92.4 pounds[/tex]
Another conversion factor used:
1 stone = 14 pounds
[tex]1 pound = \frac{1}{14} stones[/tex]

Answers
Answer:
31 yards 2 feet 5 inches
Step-by-step explanation:
14 yd 1 ft 7 in
+ 16 yd 2 ft 19 in
-------------------------
30 yd 3 ft 26 in
26 inches is 2 feet and 2 inches ---> 30 yd 5 ft 2 in
5 feet is 1 yard and 2 feet ---> 31 yd 2 ft 2 in
Answer:
31 yards 2 foot 2 inches
Step-by-step explanation:
To know the full distance, we need to sum both distances unit by unit. That means, we sum yards with yards, foot with foot and inches with inches. Then we converted to the larger unit whenever possible, starting from the smaller one.
Total yards: 14 + 16 = 30 yards
Total foot: 1 + 2 = 3 foot
Total inches: 7 + 19 = 26 inches
As 12 inches are 1 feet, 12*2 = 24 inches are 1*2=2 foot. Therefore, as 26 = 12*2 + 2, 26 inches are 2 foot and 2 inches.
Now we have 3 + 2 = 5 foot.
As 3 foot are 1 yard, 5 foot are 1 yard and 2 foot.
Now we have 30 + 1 = 31 yards.
Getting all together, the full distance is 31 yards 2 foot 2 inches

What is the value of arccos (-1/2)
Answers
Answer:
120° & 240° (given the angles are between 0° and 360°)
Step-by-step explanation:
We want to find [tex]arccos(-\frac{1}{2})[/tex].
This means we want to know the angle(s) for which cosine has a value of [tex]-\frac{1}{2}[/tex].
The basic acute angle that has a cosine of [tex]\frac{1}{2}[/tex] is 60°. But we want to know NEGATIVE [tex]\frac{1}{2}[/tex]. So in which quadrants is cosine negative? Second and Third
The rule to find 2nd quadrant angle with known acute angle is: 180 - αThe rule to find 3rd quadrant angle with known acute angle is: 180 + αWhere α is the basic acute angle (in our case it is 60°)
So 2nd quadrant angle is 180 - 60 = 120°
and 3rd quadrant angle is 180 + 60 = 240°
Answer:
120°
Step-by-step explanation:
arccos means the inverse of cosine.
arccos (-1/2) ⇒ We can rewrite this equation as;
cosФ = 1/2 Find the value of Ф.
Ф = arccos (-1/2) ⇒ This can be calculated directly from the calculator.
arccos (-1/2) = 120°
or arccos (-1/2) = (180 + 60)
= 240°
You can have more than one value of arccos (-1/2) since the cosine is negative in the second and third quadrant.

Step-by-step explanation:
If 84% are fiction, then the fraction of these are simply the percentage over 100:
[tex]\frac{84}{100}[/tex]
Simplified down by dividing by 4:
[tex]\frac{21}{25}[/tex]
Hope this helps!
Final answer:
To convert 84% to a fraction, divide 84 and 100 by their greatest common divisor, which is 4, resulting in the simplified fraction 21/25 representing the part of Astrid's books that are fiction.
Explanation:
To convert the percentage of Astrid's books that are fiction into a fraction, we simply write the percentage as a ratio out of 100 and then simplify it. Since 84% of her books are fiction, we start with the fraction 84/100. This fraction can be simplified by dividing both the numerator and the denominator by the greatest common divisor, which is 4 in this case.
84 ÷4 = 21
100 ÷ 4 = 25
Therefore, the simplified fraction of Astrid's books that are fiction is 21/25.

Marcus has $28 to spend. He spent $3.75 to buy a notebook. He needs to save $11.25 but he wants to buy a snack. Chips cost $1.30 per package. Tax has already been included in the price. What is the maximum number of packages that Marcus can buy? Write an inequality that represents the situation. Then solve your inequality by showing your work and steps.
Answers
Total money Marcus has = $28
Money spent to buy a notebook = $3.75
Money left now = [tex]28-3.75=24.25[/tex]
Money needed to be saved = $11.25
So, the amount of money Marcus can spend = [tex]24.25-11.25=13[/tex]
Cost of a packet of chips = $1.30
The inequality to determine the maximum number of chips he can buy is:
Let the number of chips Marcus can buy = x
As he cannot spend more than $13 to buy chips so equation becomes:
[tex]1.30x\leq 13[/tex]
Solving this we get
[tex]x\leq 10[/tex]
Hence, Marcus can buy a maximum of 10 packs of chips and save $11.25

An airplane climbs at an angle of 11 degrees with the ground. Find the distance it has traveled when it has attained an altitude of 400 feet. Using sin, cos, and tan.
Answers
The distance traveled by the airplane to attain an altitude of 400 feet is approximately 2164.8 feet.
Explanation:To find the distance traveled by the airplane, we can use trigonometric functions.
Let's use the side opposite the angle as the altitude (400 feet) and the hypotenuse as the distance traveled.
Using the sine function, we can solve for the distance:
sin(angle) = Opposite / Hypotenuse
sin(11 degrees) = 400 feet / x
x = 400 feet / sin(11 degrees)
Using a calculator, we find that x ≈ 2164.8 feet.
Therefore, the distance traveled by the airplane to attain an altitude of 400 feet is approximately 2164.8 feet.
The distance it has traveled when it has attained an altitude of 400 feet is 2096.34 feet.
Given, Climbing angle [tex](\(\theta\))[/tex] = 11°
Altitude (opposite side) = 400 feet
sin(angle)= opposite/hypotenuse
sin(11°)= 400/d
d=400/ sin(11°)= 0.1908/400 ≈ 2096.34
The airplane has traveled approximately 2096.34 feet when it has attained an altitude of 400 feet at an angle of 11° with the ground.
