Hey! So this is pretty straightforward. You're given all the information already and now you just have to do some calculations.
60 + 30w = 480
You can start by subtracting 60 from both sides
30w = 420
Now you need to get w by itself so you have to divide both sides by 30 and you will end up getting
w = 14!

The answer choices are in cubic inches, so convert the dimension that is given as feet into inches.
1 foot = 12 inches, so multiply 3.1 feet by 12:
3.1 x 12 = 37.2 inches.
Now multiply the three dimensions to find the volume:
15 x 37.2 x 7 = 3,906 in^3
Answer:
The x-value is -2
Step-by-step explanation:
U can substitute any of the equations for y
-5x + (-9) = 2x + 5
-9 = 7x + 5
-14 = 7x
-2 = x
x = 2

Answer:
c = 5.00w +3.10g
Step-by-step explanation:
Let w represent the number of car washes purchased, g represent the number of gallons of gas purchased, and c represent the total cost of the trip.
cost = (cost of car washes) + (cost of gas)
c = 5.00w + 3.10g
