Answer:
Explanation:
This problem is asking you to substitute for x.
1. 38.1 + x when x=-6.1
It is giving you what the value of x is, -6.1.
Substitute
38.1 - 6.1
=32
When ever it says x =
That number replaces x and then you solve.
2. 18.7 + x x = 8.5
18.7 + 8.5
27.2
Do this for the rest of the problems.
Hope this helps!!!
