<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:
Therefore, the answer is D. 5 hours.

Step-by-step explanation:
-10x + 4 = -7x - 14 - 7x - 14
-10x + 4 = -14x - 28
4x = -32
x = -8.
Answer:
Graph F
Step-by-step explanation:
Given
x + 3 < 7 ( subtract 3 from both sides )
x < 4
Since x is less than 4 then this is indicated by an open circle at 4 on the number line with the arrow pointing to the left as shown on graph F
