Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.

This means 5x + 8x = 13x and -7 - 55 = -62

The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.

13.3

Step-by-step explanation:

There is an equation that helps

2.) divided by 6 (because there is 6 numbers in the data)

3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)

which in this case it should be 13.33333...=13.3
