Answer:
32 water bottles
Step-by-step explanation:
8x=425-175
425-175=250
250 is how much more they need.
8x=250
x=31.25
You can't have half of a bottle... so round up to at least 32 water bottles
Answer:
14.6
Explanation:
It's pretty simple if you use a calculator, have a nice day and good luck with your work! <3
Each ride has a fixed cost of 7 and a cost that increases proportionally to the distance travelled of 0.25 per mile. Therefore the total cost of the ride is:

Where "x" is the distance in miles. Marco can only spend 30 on his ride, therefore the cost must be less or equal to that value.

We can solve the linear equation by isolating the "x" variable on the left side.

Marco's travel must be shorter or equal to 92 miles.
2y-4=3y-5
-4=y-5
1=y
Answer: y=1
Answer:
You would first add 3 to 12 - 6x =15
x =2.5
12(2.5) = 30
Final value =38
