Jonas Pollard · Answer 1

A.

We want an inequality whose answer is w<5.2

B.

If we were given the inequality, "w<5.2" would be the last step of a sequence of simplification steps.

C. Let's reverse the process, by adding or multiplying:

w<5.2

add 0.8 to both sides:

w+0.8 < 6

multiply by 3:

3w+2.4 < 18

multiply by - 1:

-3w-2.4>-18

add 5w to both sides:

2w-2.4>5w-18

Answer: by reversing the process of solving an inequality, as in the example shown.
