Answer:
56 hours
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
x -----> the number of hours
y ----> the amount earned in dollars
This problem represent a proportional relationship between the variable x and the variable y
Find the value of the constant of proportionality k
For (3,27) ----> 
For (9,81) ----> 
For (21,189) ----> 
The constant of proportionality k is 9
The linear equation is
For y=$500
substitute in the equation and solve for x
Divide by 9 both sides
To solve this problem, we are going to use a scientific/mathematics strategy called Dimensional Analysis.
40 miles / 1 hour * 5280 feet / 1 mile = 211200 feet / 1 hour
211200 feet / 1 hour * 1 hour / 60 minutes = 3520 feet/ 1 minute
3520 feet / 1 minute * 1 minute / 60 seconds = approximately 59 feet / 1 second

Answer:
y = -2x + 3
Step-by-step explanation:
m = -2
y = -2x + b
3 = 0 + b
b = 3
y = -2x + 3

The answer is 166
Step-by-step explanation:
x+90+24
A good deal on the mortgage I suppose. A bit expensive, but if you have the money go for it.
