Answer:
28
Step-by-step explanation:
Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs
so the car travelled 2686 miles in 96 hours
2686/96= 27.9791666667
So the car's average speed is about 28
1st number = x
2nd number = 3x
3rd number = 2x-10
x +3x + 2x-10 =92
6x - 10 = 92
6x =102
x = 102/6
x = 17
1st number = 17
2nd number = 17*3 = 51
3rd number = 17 *2 = 34-10 = 24
17 + 51 + 24 = 92
3 numbers are 17, 51 and 24
<u>Statement</u><u>:</u>
The base of a triangle is 3m and its height is 
m.

-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
the value of the dimes is 10(21 - 5)
hope this helps
