2001 gallons used in 5 days, so the average for one day is 2001/5=400.2 gallons.
im in middle school taking algebra 1 rn, but im pretty sure the equation is similar to 40x(40 pledges every mile) + 250(how much he already has from running) = y(the unknown variable).
so the equation would be 40x+250=y and you solve that to get the expression of how much he makes per mile
Answer:
S
Step-by-step explanation:
Answer:
- Infinitely many solutions
Step-by-step explanation:
<u>Given system:</u>
<u>Divide the first equation by 2 and rearrange:</u>
- 2y/2 = 14/2 - 2x/2
- y = 7 - x
- y = -x + 7
We got the same equation with the second one. It means we have two of the same lines overlapping.
This gives us infinitely many solutions.
