Answer: You could drive 1120 miles with 40 gallons of gas. The car's gas mileage is 28 miles on a gallon of gas.
Answer:
C. x=4,y=9
Step-by-step explanation:
The given information show that
x+11y=103 (1)
9x+10y=126 (2)
Isolate x from (1)
x=103-11y
Substitute x=103-11y into (2)
9(103-11y)+10y=126
927-99y+10y=126
-89y=-801
y=9
So x=103-11x9=4
I assume you're familiar with the limit
for
. We write the given limit in this form:
The limit on the RHS is 1, so we're left with -2.
Check the picture below.
running a perpendicular line like so from the right-angle, makes three similar triangles, the large, containing the smaller ones, and a medium and a small one. Now, using proportions, you can just use there, the medium and smalle to get "x".
-47, -31, 16, 36 - No real explaination, -47 is the lowest of them all the 36 is the highest number of them all.
