Deon used 5 1/3 gallons of gas on Sunday and 4 5/8 gallons of gas on Monday. How many gallons did he use on the two days combined?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
