What is m ZSRW?

- 18
- 54
- 126
- 108

126

Step-by-step explanation:

Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.

Finding angles in function of X:

Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So

So

Angle SRW:

Supplementary with 54. So

54 + SRW = 180

SRW = 180 - 54 = 126

So 126 is the answer.

They need to sell 9400 pies to reach the break-order point

Step-by-step explanation:

* Lets explain the break-order point

- The break-order point is the point at which total cost and total

  revenue are equal

∴ The total cost = The total revenue

* Lets solve the problem

∵ The equation of the total cost is y = 0.65x + 1410

∵ The revenue equation is y = 0.8x

- To find the break-order point equate the two equations

∴ 0.65x + 1410 = 0.8x

- Subtract 0.65x from both sides

∴ 1410 = 0.8x - 0.65x

∴ 0.15x = 1410

- Divide both sides by 0.15

∴ x = 1410/0.15 = 9400

∵ x is the number of pies

* They need to sell 9400 pies to reach the break-order point
