You have 7/8 of a pizza left over from a party. You would like to give each friend 1/4 of the pizza. How many friend can you give 1/4 of the pizza

ughhh, i want some pizza.

thats not a system of equations, that is a solution

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
