Dominique buys $14.95 worth of gasoline for her car. if the gas station charges $1.43 per gallon, how many gallons did she get? round to the nearest tenth.

I'm going to represent this situation as an equation:

x = the number of gallons

y = the total cost

1.42x = y

1.42x = 14.95

[They charge $1.43 per gallon(x), and she payed a total (y) of $14.95]

You need to find the number of gallons or "x".

To do so, you isolate "x" in the equation:

1.42x = 14.95     Divide 1.42 on both sides (or divide 14.95 by 1.42)

x = 10.5    She got 10.5 gallons

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
