A fish tank is being filled with water. The water is rising in a linear patten. At 2:00 p. m. the tank had 5.4 gallons of water in it. At 3:30 p. m. the tank had 6.6 gallons of
water in it. At this rate, how many gallons of water will it have at 7 p. m.?

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:

c

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392
