It’s C. I have to put more letters just ignore this

if x=10 y=-2 and z=-5 then...

we solve this to get...
<em>65</em>
therefore the answer to your question would be 65
hope this helped-have a good day bro cya)
Answer:
We need to see the graph to answer this question
1/10x + 6 = 2/5x
6 = 2/5x - 1/10x
6 = 4/10x - 1/10x
6 = 3/10x
6 / (3/10) = x
6 * 10/3 = x
60/3 = x
20 = x <=== the gas tank can hold 20 gallons
I would but my teacher has a ad blocker on and I cant access the attachment :P
