The van's consumption is 200/10 = 20 miles per gallon
so for 480 miles we need 480 / 20 = 24 gallons
Answer:
448
Step-by-step explanation:
7 x 2 x 2 x 2 x 2 x 2 x 2 = 448
Use rise over run to find slope. If you don't know what that is, its y2-y1/x2-x1. Y2 is 125, Y1 is 25, X2 is 5, and X1 is 1. You then plug the numbers in, 125-25=100. 5-1=4. then you divide 100/4, in which you get 25. So you times 25 by 3, getting 75.
X+y= -12
xy=8
y=8/x
x+8/x=-12
x^2+12x+8=0
This has no integral
