45:9!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
29 gallons because if he uses 18 gallons to go 468 miles, he would be getting 26 mpg. 26 goes into 754 29 times, so he uses 29 gallons to go 754 miles.
36 - 100%43 - x %
we multiply by cross -> 36 * x = 100 / 43
we should remove '100%' from new value, because we find only increase.. no new value in percent.
x + 100 = (43 * 100)/36
x = 4300/36 - 100x = 119+ 16/36 -100x = 19 +4/9
the answer is
19.44% increase
-6(4x + 1) + 7x + 9(x - 3) = 4
-6(4x) - 6(1) + 7x + 9(x) - 9(3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-24x + 7x + 9x - 6 + 27 = 4
-8x + 21 = 4
- 21 - 21
-8x = -17
-8 -8
x = 2.125
I think the measure of /_ EAF is 58°
