Answer:
The total cost of resurface the path is
Step-by-step explanation:
step 1
Find the area of the path
The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool
step 2
Find the cost of resurface the path
Multiply the area of the path by $2 per square foot
Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
