Im thinking 10 because 10+40=50 and 10x7=70
14, 16, 17, 19, 20
17 is the middle one so the answer is 17
Hope this helps :)
Where are the answer choices and the rest of the question?
<span>9c+(8+3c)
9c+8+3c (collect like terms)
9c+3c+8
12c+8
12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:
12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)
4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
</span>
