Answer: -10
Step-by-step explanation:
Simplifying
-3(y + 5) = 15
Reorder the terms:
-3(5 + y) = 15
(5 * -3 + y * -3) = 15
(-15 + -3y) = 15
Solving
-15 + -3y = 15
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + -3y = 15 + 15
Combine like terms: -15 + 15 = 0
0 + -3y = 15 + 15
-3y = 15 + 15
Combine like terms: 15 + 15 = 30
-3y = 30
Divide each side by '-3'.
y = -10

Answer:
4400 miles
Step-by-step explanation:
2200 x 2.0 = 4400
Answer:
This is the answer of your question.
Using the equation y=6x+12, where x is the number of hours and y is the total cost for the given value of x, you can plug in 42 for y and solve:
42=6x+12
42-12=6x
30/6=x
5=x
Thus, Amy can rent the bike for 5 hours.
