Answer: the number = 6

Step-by-step explanation:

Let x be the number.

Set equation according to the information given

2 + 8x = 2 × 25

Simplify by multiplication

2 + 8x = 50

Subtract 2 on both sides

2 + 8x - 2 = 50 - 2

8x = 48

Divide 8 on both sides

8x / 8 = 48 / 8

$\boxed {x=6}$

Hope this helps!! :)

A bus driver follows a morning route and an afternoon route each day. Because there are more cities on the morning route, the av

lisov135 [29]

Answer: The correct option is B, i.e., 40 miles per hour.

Explanation:

Let the speed of bus in the afternoon route be x.

From the given information the average speed is 12 miles per hour less than the afternoon route. So, the speed of bus in the morning route is x-12.

$\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total Time}}$

So,

$\text{Total Time}=\frac{\text{Total Distance}}{\text{Average Speed}}$

Time taken by bus in morning route is,

$\text{Total Time}=\frac{70}{x-12}$

Time taken by bus in afternoon route is,

$\text{Total Time}=\frac{100}{x}$

Since it is given that the time is same, so

$\frac{70}{x-12}=\frac{100}{x}$

$70x=100(x-12)$

$70x=100x-1200$

$30x=1200$

$x=40$

Since x represents the speed of bus in afternoon route, therefore the correct option is B, i.e., 40 miles per hour.

Show how to solve 6/15=2/?

Bas_tet [7]

There are two way sof doing this question:
1st solution is : 
 6/15 = 2/5
because 6/15 is divisible by 3 and it is done by this form :
 3 X 2 = 6
 and
 3 X 5 = 15
2nd solution is:
6/15 = 2/?
here we suppose that the missing value is x:
 6/15 = 2/x
you shift the denominators and then multiply them by the their numerators:
6 * x = 15 * 2
 6x = 30
now you divide 6 on both sides:
 6x/6 = 30/6
 x = 5
