.75 mi/minute
45/60=.75
.75 miles every minute
there are 3960 feet per minute.
You could also times 45 by 5280, since there are 5280 feet in a mile, and you would get 237,600. You would then divide it by 60, and still end up with 3960 feet per minute.

Answer:
x = -4; y = -3
Step-by-step explanation:
2x - 5y = 7
3x - y = -9
Rewrite top equation. Multiply both sides of bottom equation by -5. Add equations. This eliminates y, and we solve for x.
2x - 5y = 7
(+) -15x + 5y = 45
----------------------------
-13x = 52
Divide both sides by -13.
x = -4
Substitute -4 for x in the first original equation and solve for y.
2x - 5y = 7
2(-4) - 5y = 7
-8 - 5y = 7
-5y = 15
y = -3
Answer: x = -4; y = -3
-5 =
The answer would be — m>/-3
