Answer:
There is no question.. Why?
5x + 8 = 4
5x = -4
x = -4/5
3(-4/5) = -2.4
Solution: 3x = -2.4
Hello!
As we know, Distance is found by the standard formula of: D = RT. This tells us that Distance is equal to the Rate (of speed) multiplied by the Time driven at that speed. A simple re-arraignment of the formula is all that is required to find any one of the three terms if the other two quantities are known.
<span>As you are trying to determine how long the trip will take, the Time, you must divide the Distance by the Rate of speed you are traveling. This equation will be: T = D/R. </span>
<span>To determine the Rate of speed, the Distance is divided by the Time the trip took: R = D/T. </span>
<span>There you have it, Blackbetty, three equations to calculate which ever of the three unknowns that is needed. This should help you with this problem. Let us know if you have any more questions!
</span>
For more info:
The original formula for distance is:
<span>d = distance </span>
<span>r = rate </span>
<span>t = time </span>
<span>d = rt </span>
<span>If you want to know distance, use: </span>
<span>d = rt </span>
<span>If you want to know the rate, use: </span>
<span>r = d / t </span>
<span>If you want to know the time, use: </span>
<span>t = d / r </span>
<span>The answer is t = d / r

Hope this Helps! Have A Wonderful Day! :)
To add distances, lay them end-to-end in the same direction.
To subtract distance, lay the negatve one along the positive one so their ends lie at the same point.
_____
The attachment gives the general idea of the layout. You draw the negative distances on the same line. (Here, they're shown parallel for clarity.) You must set your compass or dividers to the distances given on your page.
It would be convenient to mark a beginning spot near the left end of each given line. I would do this exercise by marking the "a" distance on all the lines to begin with, then set the compass or dividers to "b" and add or subtract it the required number of times, then set the compass or dividers to "c" and add or subtract that in the two places required.
You must be careful not to disturb the distance setting of the compass or dividers after you set the desired length. Put one point of the instrument on the beginning mark, then use the instrument to make a mark where the end of the segment lies. Use this mark to add or subtract additional segments as required.
