Malloy solved the equation −5x − 16 = 8; his work is shown below. identify the error and where it was made.

−5x − 16 = 8
step 1: −5x − 16 + 16 = 8 + 16
step 2: −5x = 24
step 3: negative five times x over five = twenty-four over five
step 4: x = twenty-four over five

-5x-16=8

-5x=24

above is how to correctly solve the equation

The error is in step 3.

Step 3 as written:

This is incorrect because you are removing the 5 from the -5x so it wouldn't be in the numerator.

Hope this helps

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."
