Answer:

8 + 1.5x + 0.75y = pizza_cost

Step-by-step explanation:

It is given that every 10-inch cheese pizza costs ($8), meaning that this will be the constant.

Let (x) represent the number of inches added to the pizza. Since each extra additional inch costs ($1.5) thus one adds (1.5x) to the equation.

Let (y) represent the number of toppings. Every extra topping costs ($0.75) therefore one has to add (0.75y) to the equation.

Putting all of the elements together one gets the equation,

8 + 1.5x + 0.75y

10. Solve for z: 2 + 8 - z = -24
iVinArrow [24]

Answer:

The answer is z = 34.

Step-by-step explanation:

1) Simplify 2 + 8 - z to 10 - z.

10 - z =  - 24

2) Subtract 10 from both sides.

- z =  - 24 - 10

3) Simplify - 24 - 10 to -34.

- z =  - 34

4) Multiply both sides by -1.

z = 34

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>z</u><u> </u><u>=</u><u> </u><u>34</u><u>.</u>
