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, ∞ )
