What is the value of x and y?

x = 5/4

y = 15/16

Step-by-step explanation:

y = 3/4x

5/2 x + 2y = 5

Substitute the first equation into the second equation

5/2x + 2(3/4x) = 5

5/2x + 3/2x = 5

Combine like terms

8/2x = 5

4x = 5

Divide by 4

4x/4 = 5/4

x = 5/4

Now find y

y = 3/4 x = 3/4 ( 5/4) = 15/16

no not all of them.

step-by-step explanation:

some of them have a square base.
