Cost/gallon
67.50/23 = x/1
23x = 67.50
23x/23 = 67.50/23
x = 2.93
they spent approximately $2.93 per gallon on gas
Answer:
x=-1
Step-by-step explanation:
General equation of line is y=mx+n where m is slope. So, if we use point (-4, 8) and slope in equation we have 8= 2/3.(-4)+n
Then we have n=8+8/3, that is n=32/3
Therefore equation of our line is y=2/3.x + 32/3
For the point (x,10) in equation 10=2/3.x + 32/3
Then we have 2/3.x = - 2/3 then x= -1
