Answer:
a) y = 9x
b) For every increase of 1 hour the price to rent the lane increases by $9.
c) $27
Step-by-step explanation:
a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.
So, the equation would look like this:
y = 9x
b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.
c) Plug 3 into the equation:
y = 9(3)
y = 27
Therefore, it costs $27 to rent the lane for 3 hours.

Answer:
20 minutes on the stationary bike
10 minutes on the treadmill
Step-by-step explanation:
x = minutes on bike
y = minutes on treadmill
x + y = 30
12x + 15y = 390
x = 30-y
12(30-y) + 15y = 390
360 - 12y + 15y = 390
3y = 30
y = 10
x + 10 = 30
x = 20
(a) a rectangular prism
each one has dimensions l = 2.4 ,w = 1.2 / 3 = 0.4 and h = 1.8 / 3 = 0.6 m
(b) total volume of concrete needed is 6 * 2.4 * 0.4 * 0.6 = 3.456 m^3
Answer:
4(x + 2)
Step-by-step explanation:
Factor out common factors from each term. Note the factors for each number
4: 1, 2, 4
8: 1, 2, 4, 8
The largest factor for each is 4, and so divide 4 from both terms.
(4x + 8)/4 = (x + 2)
4(x + 2) is your factored expression.
