Bernardo is planning a 1,975 miles trip to St. Louis to visit a college. His car averages 25 miles per gallon. How
many gallons of gas will he use on the trip?

79 Gallons

Step-by-step explanation: if you divide the amount of miles by the miles per gallon you will find your answer. 1975/25=79

79

Step-by-step explanation:

If you divide 75 by 25 you get 3. Then 1900 divided by 25 equals 76. Finally add 76 by 3, you get 79.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

answer: b
