128 < 8r
/8 /8
-------------
16 < r
Answer:
r>16
Step-by-step explanation:
1.) Add 11 to both sides.
-9+1<8(r-17)−9+1<8(r−17)
2.) Simplify -9+1−9+1 to -8−8.
-8<8(r-17)−8<8(r−17)
3.) Divide both sides by 88.
-1<r-17−1<r−17
4.) Add 1717 to both sides.
-1+17<r−1+17<r
5.) Simplify -1+17−1+17 to 16.
16<r16<r
6.) Switch sides.
r>16r
