Answer:
7a
Step-by-step explanation:
We don't actually know the variable A and we don't have a final product to help us solve it, so the best we can do is make 7 a coefficient to the variable A, making the answer 7a.
Answer:
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-4</u></em>
Step-by-step explanation:
First Expand :
6(x - 3)
= 6x - 18
Now you need to Simplify:
6x - 18 = -42
And now get the 6x by itself by doing this :
6x - 18 = -42
+18 +18
= > 6x = -24
And 6 x 4 = 24
But 6 x -4 = -24
So :
6x/6 and -24/6
= >> x = -4
The speed of the train in miles per hour which is the ratio of the total distance covered and the total time taken to cover the distance is 9.79 mph
- Total distance covered = 7 and 5/6 miles = 7.83333 miles
- Total time taken = 4/5 of an hour = 0.8 hour
Recall :
Speed in miles per hour = Distance covered / time taken
- The speed of the train = 7.833333 ÷ 0.8 = 9.7916
- The speed of the train in miles per hour = 9.79 mph
Therefore, the speed of the train in miles per hour as calculated from the distance covered by the train over a certain period of time is 9.79 mph
