Answer:
m=-30
Step-by-step explanation:
2m+10=5m+100
get rid of 2m by subtracting
10=3m+100
get rid of 100 by subtracting
-90=3m
divide by 3
-30=m
m=-30
15 with a remainder of 2
So the third answer
It’s also equal to 15.66 or 15 and 2/3
Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
Answer:
A:B:C = 5:5:7 or 5x : 5x : 7x
Cindy ate 30 Skittles less than Ann and Ben together
-----> 7x = 5x + 5x - 30
-3x = -30
x = 10
5x = 50
7x = 70
They ate 50+50+70 = 170 of them
