Step-by-step explanation:
5 dollars * 14 stores= $70
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
The 2md number can be y. This makes the first number 1/5 of y
Your equation is y + 1/5y = 30
You can randomly plug in numbers and you get that the first number is 5. This means that the second number is 25
1) -10, 0
2) 20
4) 24 minutes
7) 25 floors
10) 9 baskets ( I'm not great at GCF )

Hope this helps. Sorry if I got some wrong (specifically 10)
