Question

Evaluate the expression 8.2x- 6.1 when x=7

Answer 1

51.3

Explanation:

Since it's telling us that (x=7) then that means 8.2x is going to be multiplied

8.2(7) or 8.2 x 7.

Then you end up getting an answer of 57.4

But you are not finished yet and need to subtract 6.1

so 57.4 - 6.1 = 51.3

And your result will be (51.3)

I hope this helps you understand this problem!
