Suppose you drive an average of 12,000 miles per year, and your car gets 25 miles per gallon. Suppose gasoline costs $3.40 a gallon
a. How much money do you spend each year on gasoline?
b. You plan to trade in your car for one that gets x more miles per gallon. Write an expression to represent the new yearly cost of gasoline.
c. Write an expression to represent your total savings on gasoline per year.
d. Suppose you can save $400 a year with the new car. How many miles per gallon does the new car get?
a. You spend $ each year on gasoline.
(Simplify your answer.)

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16

i have no clue i hate math i just need the points to get my answers
