<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.

X-70/x&lt;-3 solve for x under the assumption that x&gt;0
Virty [35]

<span>Simplifying 0x + 7 + 5x = 2x + 30 + 40 Anything times zero is zero. 0x + 7 + 5x = 2x + 30 + 40 Combine like terms: 0 + 7 = 7 7 + 5x = 2x + 30 + 40 Reorder the terms: 7 + 5x = 30 + 40 + 2x Combine like terms: 30 + 40 = 70 7 + 5x = 70 + 2x Solving 7 + 5x = 70 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. 7 + 5x + -2x = 70 + 2x + -2x Combine like terms: 5x + -2x = 3x 7 + 3x = 70 + 2x + -2x Combine like terms: 2x + -2x = 0 7 + 3x = 70 + 0 7 + 3x = 70 Add '-7' to each side of the equation. 7 + -7 + 3x = 70 + -7 Combine like terms: 7 + -7 = 0 0 + 3x = 70 + -7 3x = 70 + -7 Combine like terms: 70 + -7 = 63 3x = 63 Divide each side by '3'. x = 21 Simplifying x = 21</span>
