Answer 1
Answer:

Answer:

6. 5x+15

Step-by-step explanation:

Distributive property would be the first thing to do, so

-3(2x-5+x)

-6x + 15 -3 x

12x-6x-5-3x+2x

Combine all like terms which are, 12x-6x=6x-3x=3x+2x=5x, and the positive fifteen doesn't have any like terms so we leave that just as it is

5x+15 should be the answer

Average = (18.6 + 18.5) / 2

Average = 37.1/2

Average = 18.55

Thus,

The midpoint is 18.55.
