I think Deal B correct me if im wrong..
Answer:
r ≥ -1. it is A because r is greater than or equal to -1.
I am sorry <u>if</u> I got it wrong.
Step-by-step explanation:
3r+2(12r+7) ≤ 5r-8
27r+14 ≤ 5r-8
I subtract 27r and 5r.
22r+14 ≤ -8
I subtract 14 and -8.
22r ≤ -22
Divide 22 on both side.
r ≥ -1
I think it is $10 for 20%
No, it’ll be just 49 not negative 49. Because you times they by it’s self and the negatives cancel eachother !
