*HELP!* Mia buys 3 gallons of gas that costs d dollars per gallon. Bob buys g gallons of gas that costs $3 per gallon.

a. Write an expression for the amount Mia Pays for gas.

b. Write an expression for the amount Bob pays for gas.

what both people pay?

mias expression looks like 3*D=amount paid

bobs expression looks like G*3=amount paid

if we new how much they paid then we could figure out how much it costs or how much they got

for mia the 3 represents the number of gallons and for bob the three represents how much he paid

Step-by-step explanation:

lol we need to see what the question is asking about

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
