(I NEED AN EXPLANATION ON HOW YOU GOT THE ANSWER
PLEASE AND thank you)

Answer 1

A. 5x > 20

Explanation:

Total production by 5 machines: 5x

5x > 20

Answer 2

A

Explanation:

We know that each machine makes x fixtures and we have 5 machines. So we need to use multiplication:

5 * x = 5x

The above expression indicates how many fixtures the 5 machines can make. We want the total to be more than 20, so we need to use the greater than sign: >.

5x > 20

The answer is A.
