Question

What is the range pls help me (11points).

Answer 1

2.3 < x < 8.7

Explanation:

Look at the picture.

We have a = 5.5, b = x and c = 3.2.

Substitute:

(1)

5.5 + x > 3.2 subtract 5.5 from both sides

x > - 2.3

(2)

5.5 + 3.2 > x

8.7 > x

(3)

x + 3.2 > 5.5 subtract 3.2 from both sides

x > 2.3

From (1), (2) and (3) we have:

2.3 < x < 8.7
