Answer:
1,260
Step-by-step explanation:
Let's name
LT = number of long term parking spaces
ST = number of short term parking spaces
CP = the number of parking spaces in the cell phone parking
We have
LT/ST = 5/7
ST/CP = 8/9 or CP/ST = 9/8
LT + ST + CP = 3180
Dividing the last equation by ST we get
LT/ST + 1 + CP/ST = 3180/ST
replacing
5/7 + 1 + 9/8 = 3180/ST
Solving for ST we obtain ST = 1,120.
Replacing in the second equation, we get CP/1,120 = 9/8,
hence CP = 1,260
Answer:

Answer:
y=20x+25, this equation is linear, the rate of change is constant
Step-by-step explanation:
She starts with 25$, that doesn't change so its our constant. Let x represent each week. Each week she ears 20$
So, let y represent the total amount of money she has
y=20x+25, this equation is linear, the rate of change is constant

Answer: 355 Millileters
Answer:
h(x) = 1/4 x - 2
Step-by-step explanation:
f(x) = 4x + 8
y = 4x + 8
x = 4y + 8
4y = x - 8
y = 1/4 x - 2
h(x) = 1/4 x - 2
