First make the dash an x. Then move over to the other side of the = so it looks like this:
-5=-13-x
You take -13 to the other side of the equal sign so it looks like this:
-5+13=-x
Then:
8=-x or x=-8
Hopefully that makes sense.

Jessica ran on the track team at her school. She finished the 200-meter race in 54 seconds. What was jessica's average speed,in

Scrat [10]

Answer:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Step-by-step explanation:

The problem provides for this case the amount of distance travelled by Jessica in a given time. And we know that travels 200m in 54 seconds.

We want to find the average speed and we can use the following formula:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race
