M + 5f = 25....multiply by -1
m + 10f = 40
----------------
-m - 5f = -25 (result of multiplying by -1)
m + 10f = 40
-----------------add
5f = 15
f = 3
m + 10f = 40
m + 10(3) = 40
m + 30 = 40
m = 40 - 30
m = 10
so the membership fee (m) = 10 and the sessions(f) = 3
Answer:
7.
Step-by-step explanation:
-10 /(3 + 2) + 9
= -10 /5 + 9
= -2 + 9
= 7.
Answer:
B
Step-by-step explanation:
All you have to basically do on this one is go backwards.
The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).
12-4=8
Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.
8/4=2
Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12
Hope this helped!
