Answer:
you are adding a dollar and 50 cents each time
Step-by-step explanation:
then find your y and x and plot it
3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25

5 5
x = 5
R = laps she runs
s = laps she swims
each r (laps she runs) takes 5 min.
each s (laps she swims) takes 3 min.
She wants to run for 30 min.
So your inequality should = 30
