Answer:
x = $1.5, y = $2.75
Step-by-step explanation:
5x + 6y = 24
3x + 2y = 10
Solve for y
2y = 10 - 3x
y = 5 - 3/2x
Plug y into first equation
5x + 6y = 24
5x + 30 - 9x = 24
-4x = -6
x = $1.5
y = $2.75
Answer:
7 1/2
Step-by-step explanation:
2 1/2 ÷ 1/3
Change the mixed number to an improper fraction
2 1/2 = (2*2+1)/2 = 5/2
5/2 ÷ 1/3
Copy dot flip
5/2 *3/1 = 15/2
Changing back to a mixed number
2 goes into 15 7 times with 1 left over
7 1/2
150 is the perimeter of the pool
