To solve for the length of a perimeter, use
L = P/2﹣w
L = 66/2 - 7
L = 33 - 7
L = 26
The length is 26
Answer: 6 hours or 360 minutes
Step-by-step explanation:
First find out how long it takes to deliver to one house.
Convert hours to minutes.
2.5 x 60 = 150 minutes total
Divide to find the time per house
150 minutes / 130 houses = 1.15 minutes per house
Now multiply this rate by the number of houses (312).
312 x 1.15 = 360 minutes
If you want it in hours then divide by 60.
360/60 = 6 hours.

Answer:
12s +3j= 85.95
15s +2j= 93.55
Step-by-step explanation:
First, define the variables:
Let the cost of a shirt be $s and the cost of a pair of jeans be $j.
From the first sentence:
12s +3j= 85.95 -----(1)
From the second sentence:
15s +2j= 93.55 -----(2)
Answer:
r = 32
Step-by-step explanation:
R is the variable that we are trying to find.
24 = 3/4r
Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.
24 / 3/4 = 3/4r / 3/4
32 = r
Therefore, r = 32.
To check, we can plug 32 into the equation.
24 = 3/4 x 32
3/4 x 32 = 24
