Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

        x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..

Answer:

30

Step-by-step explanation:

This is an easy one.

So, we know that 40% of the class is girls. We would need to use the other 60% as 60% of the class is boys and we would need to divide.

18/0.6=30

Therefore your answer is 30.

Hope this helps.

Answer:

20

Step-by-step explanation:

It is 40 percent ( given)

18/2=9

9×5=40 (100%)

Girls- 18( given)

Boys- 40-18=22

Rounded off-20

Answer:

The value of a = 5.

the value of b = 6.

Step-by-step explanation:

Given the points on the line

Given that all of the points are on the same line and the line represents a linear function.

Thus, the slope between any two points must be the same.

First, determine the slope between (6, 10) and (2, 2)

(x₁, y₁) = (6, 10)

(x₂, y₂) = (2, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 10] / [2 - 6]

               = -8 / -4  

               = 2

Thus, the slope of the line = m = 2

Determine the value 'a'

(x₁, y₁) = (6, 10)

(x₂, y₂) = (a, 8)

Using the slope formula to determine the value of 'a'

Slope =  [y₂ - y₁] /  [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula

Slope =  [y₂ - y₁] /  [x₂ - x₁]

2 = [8 - 10] / [a - 6]

2(a - 6) = 8 - 10

2a - 12 = -2

2a = -2 + 12

2a = 10

divide both sides by 2

a = 5

Therefore, the value of a = 5.

Determine the value 'b'

(x₁, y₁) = (2, 2)

(x₂, y₂) = (4, b)

Using the slope formula to determine the value of 'b'

Slope =  [y₂ - y₁] /  [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula

Slope =  [y₂ - y₁] /  [x₂ - x₁]

2 = [b - 2] / [4 - 2]

2(4 - 2) = b - 2

8 - 4 =b - 2

4 = b - 2

b = 6

Therefore, the value of b = 6

How to solve your question

Your question is 13 + 3 − 8x + 6 = 1 − 5x

13 +3 - 8x + 6 = 1 - 5x

13 + 3 − 8x + 6 = 1 − 5x

Solve

Add the numbers

13 + 3 − 8x + 6 = 1 − 5x

22 − 8x = 1 − 5x

Rearrange terms

22 − 8x = 1 − 5x

−8x + 22 = 1 − 5x

Subtract  22 from both sides of the equation

−8x + 22 −22 = −5x + 1 − 22

Simplify

Subtract the numbers

−8x = -5x + 1 -22

-8x = -5x -21

Add 5x to both sides of the equation

-8x + 5x = -5x -21 + 5x

Simplify

Combine like terms

-3x = -21

Divide both sides of the equation by the same term

(-3x)/3 = (-21)/3

Simplify

Cancel terms that are in both the numerator and denominator

x = (-21)/(-3)

Divide the numbers

x = 7

Answer:

V = 317 1/3 cubic units

Step-by-step explanation:

V = 1/3 · Area of Base · Height

V = 1/3 · 1/2(14 x 8) · 17

V = 1/3 · 56 · 17

V = 317 1/3

Answer:

x= 10

Step-by-step explanation:

Mean is the sum of all values divided their number

(8.5+ 9 + 7.5 + 6 + 7 +x) /  6 = 8

(8.5+ 9 + 7.5 + 6 + 7 +x) = 8*6 = 48

(8.5+ 9 + 7.5 + 6 + 7 +x) =48

(38 +x) = 48

x= 48-38 = 10

Answer:

90

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

x + 70 =120       {Exterior angle theorem}

        x = 120 - 70

       x = 50

y = x     {Vertically opposite angles}

y = 50

z + 50 + 40 = 180          {Angle sum property}

 z + 90  = 180

          z = 180 - 90

          z = 90
