Mr. Marquez bought 7 pizzas for his youth group and paid with a $50 bill. If the pizza deliverer gave him $6.32 in change and each pizza cost the same
amount, what was the cost in dollars and cents for each pizza?

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

47 - 90 = 43

43 - 180 = x

x = 137

2: 10

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
