Hi there
2.5x2 = 5
length x width x height
Answer:
2.89
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.
First, subtract 12 from both sides:
25 = 4.5z + 12
25 (-12) = 4.5z + 12 (-12)
25 - 12 = 4.5z
13 = 4.5z
Isolate the variable, z. Divide 4.5 from both sides:
(13)/4.5 = (4.5z)/4.5
z = 13/4.5
z = ~2.89 (rounded).
2.89 is your answer.

The equation that models the total cost is y = 100 + 22.5m
Step-by-step explanation:
Fitness member ship cost = $100
Monthly fee = $25
Discount = 10% on monthly fee
To calculate new monthly fee after discount,
25 - (25*10%) --> 25 - 2.5 --> $22.5
Number of months = m
Fee in m months = 22.5*m = 22.5m
<u>Equation:</u>
(c) is constant which is the membership fee
(x) is the monthly fee $22.5
(m) is the number of months
(y) is the total cost
So,
y = mx + c
y = m(22.5) + 100
y = 100 + 22.5m
Therefore, the equation that models the total cost is y = 100 + 22.5m
