First, we multiply the denominator to get to 9. That would be x3. We then do that to the top, and end up with the fraction 3/9, which is equivalent to 1/3.
14. A
C=10+12h
I think one time fee is 10, the recurring fee is 12
15.B
c=2*12h=24h
initial value is going to be 0 because no one time fee, rate of change is 24
C=a*h+b(a is rate of change, and b is initial value)
60 minutes in an hour x 3 hours = 180 minutes
Divide the 8 people by 180 minutes and you will have your answer!
1) Put the x value on the same side of the equation
100= 160-10x+6x
100= 160-4x
2) put 160 on the other side of the equation
100-160=-4x
-60=-4x
3) divide -4 on both sides
-60/-4= -4x/-4
15=x
Hope this helps!
If the groups are all made up of 10 pennies and she added 5 groups, then
5 x 10 = 50
Which means she added 50 pennies to the jar and now has 150 pennies. :)
