Complete Question:

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas. At this rate how many pounds of cheese are used per pizza?

Answer:

0.5 pounds of cheese are used per pizza

Solution:

Given that,

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas

Therefore,

$4.375\ pounds = 8\frac{3}{4}\ pizza \\\\4.375\ pounds = \frac{35}{4}\ pizza$

We have to find pounds used per pizza

Let "x" be the pounds used per pizza

Then,

$4.375\ pounds = \frac{35}{4}\ pizza \\\\x\ pounds = 1\ pizza$

By cross multiplying,

$4.375 \times 1 = x \times \frac{35}{4} \\\\x = 0.5$

Thus, 0.5 pounds of cheese are used per pizza

(FIXED) Can somebody help me get to x?

Hatshy [7]

18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6 / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.

3^2 + x^2 = 14^2

9 + x^2 = 196

x^2 = 187

x = sqrt(187)
