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.

Please help I dont understand ​
Studentka2010 [4]

Step-by-step explanation:

When it says y varies directly with x it just means that y and x are proportional/equal to each other. The constant of variation and the constant of proportionality are the same thing just different way of saying it so they can confuse you and make your life miserable. Since y and x are proportional to each other and the constant of proportionalty is -5 to make an equation that represents a line you use the formula y=mx+b. That is the slope of the line. With that formula let's first plus in the x so we have y=m2+b. The formula for direct variation is y=kx as well that's good to know and it's good to memorize all these formulas. Math becaomes easier when you have the process down pat and you just need to plug numbers into different equations, expressions, and scenarios. Do m = [y1 - y2] / [x1 - x2] and you'll get the answer.
