Hello from MrBillDoesMath!
Answer:
m^2 + 11m - 11, which is the first choice
Discussion:
6m + (m-2)(m+7) +3 =
6m + (m^2 + 7m - 2m -14) + 3 =
(6m + 7m - 2m) + m^2 + (-14 + 3) = combine similar terms
11m + m^2 -11 =
m^2 + 11m - 11
which is the first choice
Thank you,
MrB
The last number line the correct answer!
-2a-5>3
-2a>8
a<-4
( the sign is flipped in the end because when you multiply or divide by a negative number, the sign flips the other way around)
I would simply consider saying that the answer is:
B. .533
because 8, 9-10th graders watched and 7 didn’t
Answer:
When number of games downloaded is at least 3
Step-by-step explanation:
Let x = number of games downloaded
Members = 50 + 2x
Non members = 20x
50 + 2x = 20x
50 = 20x - 2x
50 = 18x
x = 50/18
x = 2.78
At x = 2.78, both members and non members are paying the same amount
For members to make profits, the value of x must be greater than 2.78
Approximately x = 3
Check:
Members = 50 + 2x
= 50 + 2(3)
= 50 + 6
= 56
Non members = 20x
= 20(3)
= 60
