The answer is one hundred and thirty one
-138 <span>≥ -6(6b - 7)
Start by multiplying everything within the parentheses by -6.
-138 </span><span>≥ -36b + 42
Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)
-138 - 42 </span><span>≥ -36b
-180 </span>≥ -36b
Divide both sides by -36 to find the value of b.
-180 / -36 ≥ b
5 ≥ b.
The answer is b ≤ 5.

M = r + 3
a = 2m......a = 2(r + 3).....a = 2r + 6
m + r + a = 57
(r + 3) + r + (2r + 6) = 57
4r + 9 = 57
4r = 57 - 9
4r = 48
r = 48/4
r = 12.......rahfat is 12
a = 2r + 6
a = 2(12) + 6
a = 24 + 6
a = 30.......aurello is 30
m = r + 3
m = 12 + 3
m = 15 <=== mel is 15
