Answer: After 5 bags of mulch, the cost for both companies will be the same.
Step-by-step explanation:
The cost for Company can be represented by the equation: y= 10m+100
The cost for Company B can be represented by the equation: y= 30m
To find the amount of mulch, their cost needs to be the same, I will solve for m
10m+100=30m
-10m 10m
100=20m
Divide both side by 20
100/20=20m/20
5=m or m=5
So after 5 bags of mulch, the total cost for both companies is the same.
You need to use the equation D=RT
First you need to solve for the rate before you can see how long it takes her to drive 648 miles.
936 miles=Rate times (13 hours)
Rate= 72 miles/hour
Since the rate is the same, you can solve for time.
D=rt 648=(72)(T) . Time=9 hours
Answer:
12500
Step-by-step explanation:
im just in middle school but if I did this correctly then it should be 12500.
first set up your equation
then do your exponents
then divide your nomonator by your denomonator
