What is the soultion of - 21 = n - 8 what is n

xenn [34]

This is a simple equation:)
We have to isolate "n" to be alone.
-21 = n - 8

First add 8 to both sides.
-21 = n - 8
+8 = + 8 it cancels out on the right side of the equal side and you solve on the left side

soooo
-21 + 8 = -13
-13 = n

Finally our answer is
-13 = n

I don’t understand this problem at all.

<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />

The equation should be:

(70x) - (20x) = 250

Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.

Use an educated guess. I'm going to go with 5 because it seems reasonable.

(70 * 5) - (20 * 5) = 250

Let's check to see if it equals 250:

70 * 5 = 350

20 * 5 = 100

350 - 100 = 250

Therefore, the answer is D. 5 hours.
