32/8 = 28/x Please select the best answer from the choices provided

A: x = 4
B: x = 28
C: x = 8
D: x = 7

32/8=28/x

we multiply by x

x*32/8=28

we multiply by 8/32

x=28*8/32

8 divides by 32

x=28/4=7

D: x = 7

D

Step-by-step explanation:

Given

= ( cross- multiply )

32x = 224 ( divide both sides by 32 )

x = 7 → D

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
