Answer 6

I mean rewrite B and C into numbers
For example B would be
\(-5<n-3<2\)

Answer 7

8 < 7 -1 < 1 am i correct ?

Answer 8

Not quite, try again

Answer 9

8 times a number means 8x

8x-7+-1

Answer 11

i'll be right back

Answer 12

Okay so the sum means that you are adding what they are about to say (something + another thing)
It then says 8 times a number and 7 (8x+7)

"is between -1 and 1." is talking about the sum overall in between means its in the middle

\(-1<8x+7<1\)
