Answer:
1) 90
2) 38
Step-by-step explanation:
1) look at the attached diagram
As you can see, the floor and the wall must meet at a 90° angle.
2) Perimeter of office: 10 + 12 + 10 + 12 = 44
Subtract the door and windows' lengths:
44 - 3 - 3 = 38 ft.
Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
