Question

Which number is a solution for the inequality below?

x/4 greater than or equal to 20

A. 6
B. 16
C. 25
D. 90

Answer 1

Answer:

D 90

Step-by-step explanation:

x/4 ≥ 20

Multiply each side by 4

4*x/4 ≥ 20*4

x ≥ 80

The only number greater than or equal to 80 is 90

Answer 2

Answer: D. 90

Multiply both sides of the inequality by 4

4(X/4 )greater than or equal to (20)4

x greater than or equal to 80

So D must be the answer, since it is the only answer that is greater than 80.
