solmaris [256]

Answer:

C = (13.75 * B * H)/3750

Step-by-step explanation:

The area of a triangle is represented by the equation A = 1/2 * B * H

Every time another 3750 square feet is covered, $27.50 is spent. So, we can represent the cost using the equation C = A/3750 * 27.50

Plugging in the base and height, C = (1/2 * B * H * 27.50)/3750

C = (13.75 * B * H)/3750

What is the missing length??
amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

(15 + x) : (12 + 8) = x : 8

15 + x : 20= x : 8

Convert to fraction

\frac{15 + x}{20} = \frac{x}{8}

Cross Multiply:

(15 + x)*8 = 20 * x

120 + 8x = 20x

Collect Like Terms

20x - 8x = 120

12x = 120

Solve for x

x = \frac{120}{10}

x = 10

<em>The length of the missing side is 10</em>

What does X equal? 14x+24=18x-32
exis [7]

Answer:

x =14

Step-by-step explanation:

14x+24=18x-32

Subtract 14x from each side

14x-14x+24=18x-14x-32

24 = 4x -32

Add 32 from each side

24+32=4x-32+32

56 = 4x

Divide each side by 4

56/4 = 4x/4

14=x
