Answer:

x=-54

Step-by-step explanation:

-4(2x+9)+3x=6-4(x-3)

Reorder the terms in parentheses

+(-8x-36)+3x=6-4*(x-3)

Remove unnecessary parentheses

-8x-36+3x=+6-4+*(+x-3+)

Reorder the terms in parentheses

-8x-36+3x=6+(-4x+12)

Remove unnecessary parentheses

-8x-36+3x=+6-4x+12

move all terms containing x to the left and all other terms to the right.

-8x+3x+4x=+6+12+36

simplify left and right side of the equation.

-1x=+54

finally, divide both sides of the equation by -1 to get x.

x=-54

-4 (2x+9) + 3x = 6 - 4 (x-3)

Simplifying

-4(2x + 9) + 3x = 6 + -4(x + -3)

Reorder the terms:

-4(9 + 2x) + 3x = 6 + -4(x + -3)

(9 * -4 + 2x * -4) + 3x = 6 + -4(x + -3)

(-36 + -8x) + 3x = 6 + -4(x + -3)

Combine like terms: -8x + 3x = -5x

-36 + -5x = 6 + -4(x + -3)

Reorder the terms:

-36 + -5x = 6 + -4(-3 + x)

-36 + -5x = 6 + (-3 * -4 + x * -4)

-36 + -5x = 6 + (12 + -4x)

Combine like terms: 6 + 12 = 18

-36 + -5x = 18 + -4x

Solving

-36 + -5x = 18 + -4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4x' to each side of the equation.

-36 + -5x + 4x = 18 + -4x + 4x

Combine like terms: -5x + 4x = -1x

-36 + -1x = 18 + -4x + 4x

Combine like terms: -4x + 4x = 0

-36 + -1x = 18 + 0

-36 + -1x = 18

Add '36' to each side of the equation.

-36 + 36 + -1x = 18 + 36

Combine like terms: -36 + 36 = 0

0 + -1x = 18 + 36

-1x = 18 + 36

Combine like terms: 18 + 36 = 54

-1x = 54

Divide each side by '-1'.

x = -54

Simplifying

x = -54

Answer:

its B

Step-by-step explanation:

Sue and Jerry, working together, will take approximately 13 hours and 39 minutes to paint 10 chairs. They combine their individual rates of painting to find a total rate together and then calculate the total time needed based on that combined rate.

To determine how long it will take Sue and Jerry to paint 10 chairs, we first need to find out how long it takes for them to paint a single chair together. Sue can paint a chair in 3 hours, which is a rate of 1/3 chair per hour. Jerry paints a chair in 2 1/2 hours, or 5/2 hours, which is a rate of 2/5 chair per hour. Working together, their combined rate is (1/3) + (2/5) chairs per hour.

First, find the common denominator for the two fractions which is 15, and then add the rates together: (5/15) chair per hour (Sue) + (6/15) chair per hour (Jerry) = (11/15) chairs per hour together. To find the time to paint one chair, divide 1 chair by their combined rate:

1 chair / (11/15) chairs/hour = 15/11 hours to paint one chair together.

To find the time for 10 chairs, multiply the time it takes to paint one chair by 10:

(15/11 hours/chair) × 10 chairs = 150/11 hours = 13 hours and ≈ 39 minutes.

Therefore, Sue and Jerry together will take approximately 13 hours and 39 minutes to paint 10 chairs.

Answer: x1=-2

x2=2

Step-by-step explanation:

5x²+4x-19=4x+1

5x²+4x-19-4x-1=0

5x²-20=0

5x²=20

x²=20/5

x²=4

x1=-√4=-2

x2=+√4=2

To solve the simultaneous equations, set the two equations equal to each other, simplify, solve for x, and substitute the values of x back into one of the original equations to solve for y. The solutions are (2, 9) and (-2, -7).

To solve the simultaneous equations:

y = 5x^2 + 4x - 19

y = 4x + 1

Let's set the two equations equal to each other:

5x^2 + 4x - 19 = 4x + 1

Now, simplify and solve for x:

5x^2 + 4x - 4x - 19 - 1 = 0

5x^2 - 20 = 0

Divide both sides by 5:

x^2 - 4 = 0

Factor the equation:

(x - 2)(x + 2) = 0

Set each equation equal to zero:

x - 2 = 0 or x + 2 = 0

Solve for x:

x = 2 or x = -2

Now, substitute the values of x back into one of the original equations to solve for y:

When x = 2:

y = 5(2)^2 + 4(2) - 19

y = 20 + 8 - 19

y = 9

When x = -2:

y = 5(-2)^2 + 4(-2) - 19

y = 20 - 8 - 19

y = -7

Therefore, the solutions to the simultaneous equations are (2, 9) and (-2, -7).

The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table

Solution:

Given that concrete patio is [tex]5\frac{2}{3}[/tex] feet wide

Area of concrete patio = [tex]36\frac{2}{3}[/tex] square feet

Therefore,

[tex]\texttt{Width of concrete patio = }5\frac{2}{3}=\frac{5\times 3+2}{3}=\frac{17}{3}feet\\\\\text{Area of concrete patio = }36\frac{2}{3}=\frac{36\times 3+2}{3}=\frac{110}{3}feet^2[/tex]

Let us find the length of concrete patio

Concrete patio is usually of shape rectangle

Area of concrete patio = length x width

[tex]\frac{110}{3} = length \times \frac{17}{3}\\\\length = \frac{110}{3} \times \frac{3}{17}\\\\length = \frac{110}{17} = 6.4705 \approx 6.5[/tex]

Therefore length of concrete patio is 6.5 feet

So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table

Answer:

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  

Step-by-step explanation:

Given:

Let,

point S( x₁ , y₁) ≡ ( -1 , 1)  

point T( x₂ , y₂) ≡ (3 , -5)

Point M( x , y ) is the Mid point of segment ST.  

To Find:

Point M( x , y )= ?

Solution:

As Point M( x , y ) is the Mid point of segment ST.

So we have Mid Point Formula as

[tex]Mid\ pointM(x,y)=(\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2})[/tex]

On substituting the given values in above equation we get

[tex]M(x,y)=(\frac {-1+3}{2},\frac{-5+1}{2})\\\\M(x,y)=(\frac{2}{2},\frac{-4}{2}) \\\\M(x,y)=(1,-2)\ \textrm{which the required midpoint}[/tex]

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  

Answer:

V = 314 mm³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 10, hence r = 10 ÷ 2 = 5 and h = 4, thus

V = π × 5² × 4

   = 3.14 × 25 × 4 = 3.14 × 100 = 314 mm³

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

3x +2y = 5 → (1)

x - 2y = - 1 → (2)

Adding the 2 equations term by term will eliminate the term in y, that is

(3x + x) + (2y - 2y) = (5 - 1)

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 in either of the 2 equations and solve for y

Substituting in (1)

3(1) + 2y = 5

3 + 2y = 5 ( subtract 3 from both sides )

2y = 2 ( divide both sides by 2 )

y = 1

Solution is (1, 1 )

Answer:

0.011 (taking till hundredth decimal value)

Step-by-step explanation:

Given: 8 divided by 709.

Lets solve it by using long division.

[tex]8\div 709[/tex]

Divisor is 709 and dividend is 8.

Now, while solving we will get quotient and remainder, if any.

As in this case 709 (divisor) is smaller number than 8 (dividend).

So, we need to take decimal in quotient to add zero with the dividend, which is again smaller than divisor, therefore we will take 0 also in quotient after decimal to add more zero with dividend, now dividend have value "800".

∴[tex]800\div 709= 0.0[/tex]

In the next step, we will divide 800 by 709.

As we know, [tex]709\times 1= 709\\709\times 2= 1418[/tex]

As 709 is lesser than 800 and we don´t have value equal to 800 in the multiple of 709, therefor we will quotient as "1" .

∴ [tex]800\div 709=0.01[/tex]

Now, we have remainder [tex]800-709= 91[/tex]

we cannot divide 91 by 709, so we add zero to the dividend as we have already taken decimal.

∴ with remainder 91 and adding zero to it, make it [tex]910\div 709[/tex]

Now, we have [tex]910\div 709= 0.011[/tex]

As we know, [tex]709\times 1= 709\\709\times 2= 1418[/tex]

As 709 is lesser than 910 and we don´t have value equal to 9100 in the multiple of 709, therefor we will quotient as "1" .

∴ We have result as 0.011 (taking till hundredth decimal value)

Answer:

The graph with B(2,-3) i.e) y=[tex]\frac{-3}{2}[/tex] x goes through the point M(-10,15).

Step-by-step explanation:

Consider M(-10,15) and given that equation is y = kx.

Now, substitute M(-10,15) in the equation

⇒ 15 = k × -10

⇒ k = [tex]\frac{15}{-10}[/tex] = [tex]\frac{-3}{2}[/tex]

⇒ y = [tex]\frac{-3}{2}[/tex] x

Now, check with the given points B(2,-3) and B([tex]3\frac{1}{3}[/tex] , -2)

1) B(2,-3)

y = [tex]\frac{-3}{2}[/tex] x

⇒(-3) = [tex]\frac{-3}{2}[/tex] × 2

⇒ -3 = -3 ⇒ LHS = RHS

⇒ B(2,-3) is the required point.

2) for b([tex]3\frac{1}{3}[/tex] , -2)

LHS ≠ RHS.

So,The graph with B(2,-3) i.e) y=[tex]\frac{-3}{2}[/tex] x goes through the point M(-10,15).

Answer:

Quartile 1 (Q1) = 24

Quartile 2 (Q2) = 47

IQR = 23

Step-by-step explanation:

Given:

The set of data are:

13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

The data are in increasing order. The number terms are, [tex]n = 11[/tex].

Therefore, the middle term = [tex]\frac{n+1}{2}=\frac{11+1}{2}=6^{th}\ term[/tex]

So, the median = 26

Now, the median divides the set of data into two parts. The median of first part is the quartile 1 and the median of second part is quartile 2.

So, the first part has the following terms:

13, 23, 24, 25, 26

Here also, [tex]n=5[/tex]. So, the third term is the median.

∴ Q1 = 24

The second part has the following terms:

37, 47, 47, 48, 50

Here also, [tex]n=5[/tex]. So, the third term is the median.

∴ Q2 = 47.

Now, IQR = Q2 - Q1 = 47 - 24 = 23.

Answer:

The % of the increase in population from 1980 to 2000 will be 72.8%

Step-by-step explanation:

Let the population in the year of 1980 was x.

If the population from 1980 to 1990 has increased by 20%, then the population in the year 1990 will be [tex]x(1 + \frac{20}{100}) = 1.2x[/tex].

Now, from 1990 to 2000, the population has again increased by 20%.

So, the population in the year 2000 will be [tex]1.2x(1 + \frac{20}{100}) = 1.44x[/tex].

Again, from 2000 to 2010, the population has increased by 20%.

Therefore, the population in the year 2010 will be [tex]1.44x(1 + \frac{20}{100}) = 1.728x[/tex].

Now, the population increased from x to 1.728x between the years 1980 to 2010.

Hence, the % of the increase in population from 1980 to 2000 will be [tex](\frac{1.728x - x}{x}) \times 100\% = 72.8\%[/tex] (Answer)
