Question

16. An inequality is shown.20 < 5xSelect all the values of x that make the inequality true.45C14.5D4.

Answer 1

Tropical Tri, this is the solution:

We have the following inequality:

20 < 5x

Let's simplify it, as follows:

Dividing by 5 at both sides:

20/5 < 5x/5

4 < x or,

x > 4

In consequence,

B. 5 This value of x makes the inequality true.

D. 4 1/5 This value of x makes the inequality true.

E. 5 1/4 This value of x makes the inequality true.

Let's keep in mind that the interval that solves this inequality is:

(4, ∞ )
