Let a = runner 2, a + 500 = runner 1.
a + (a + 500) = 5000
2a + 500 = 5000
2a = 4500
a = 2250
Runner 1 ran 2,750 meters. Runner 2 ran 2,250 meters.
5(3y)-y=75 -> 15y-y=75 -> 14y= 75 -> y= 75/14
3(75/14)=x -> x= 225/14 and y= 75/14
I'm completely wrong but i tried
Answer:
ratio of adults to children in SIMPLEST form would be 3:7
Step-by-step explanation:
To simplify a ratio you have to find the Greatest Common Factor (GCF) of each number in the ratio and divide. In this example, the original ratio would be 24:56 the GCF of 24 would be 9, and the GCF of 56 would be 8. And then you would divide those numbers and get 3:7
Answer:
x=18-2/5y
y=-5/2x+45
Step-by-step explanation:
5x+2y=90
Nosotros queremos resolver para x o y
5x=90-2y
x=18-2/5y
o
2y=90-5x
y=-5/2x+45
