Solve for x

3(x-2)-2x+3=-12

help plz

x = -9

Step-by-step explanation:

First, subtract 3 from both sides of the equation and distribute the 3 to the x and -2.

3x - 6 - 2x = -15

Now, add the 6 to both sides of the equation and combine 3x and -2x.

x = -9

The value of x is -9.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

- "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."
