Answer: the two numbers are 8 and 1

Step-by-step explanation:

Let the two numbers be represented by x and y.

We derive the equations to solve the problem.

X + y = 9........equation 1

X-y =7............equation 2

Add the two equations to eliminate y

2x = 16

Divide both sides by 2

x = 16/2 = 8

If x = 8, substitute the value of x into equation 2 to get the value of y

8 - y = 7

make y the subject

8 -7 = y

1 = y

y = 1

Answer:

No, she is not correct as her speed is 0.25 miles per minute.

Step-by-step explanation:

Given:

Ratio of distance  to time taken is 15 : 60.

Distance is in miles and length of time is in minutes.

We know that, average speed is given as the ratio of the distance traveled and the length of the time taken.

So, the ratio above is nothing but the average speed of Reese for cycling.

Thus, average speed of Reese is given as:

Therefore, the average speed of Reese is 0.25 miles per minute which is not equal to the one mentioned by Reese as 4 miles per minute.

So, Reese conclusion of her average speed is incorrect. It's not 4 but the reciprocal of 4 which is 0.25 miles per minute.

Answer:

3$

Step-by-step explanation:

Because every 3 numbers are divisble by 3 and the other 2 are not. Then the chance of you winning is 66%, therefore he should pay you half of what he would make. If this makes sense.
