Question

Solve each of the given inequalities for z. Which of the inequalities have 5 as a​ solution? Inequality 1: 4(2.4z+1.25) > −14.2 Inequality 2: 2(1.6z+2.5) ≤ 11.4
What are the solutions to Inequality​ 1? Select the correct choice below and fill in the answer box to complete your choice.

Answer 1

Answer:

1.

4(2.4z+1.25) > −14.2

9.6z+ 5.00 > - 14.2

9.6z > - 14.2 - 5.00

9.6z > - 19.2

z > - 19.2/9.6

z > - 2

2.

2(1.6z+2.5) ≤ 11.4

3.2z + 5.0 ≤ 11.4

3.2z ≤ 11.4 - 5

3.2z ≤ 6.4

z ≤ 6.4/3.2

z ≤ 2
