Answer:

The numbers are 9 and 16.

Step-by-step explanation:

It is possible to solve this problem without using algebra and all the  equations. well one number is 7 more than the other, but they add to 25. If you subtract the difference of 7 first, you will be left with the sum of two equal numbers.

25-7=18

18/2=9   The one number is 9 and the other is 7 more than 9, so you would do  (9+7 = 16)

How much pay does john receive if he gives half of his pay to family,250 to his landlord and has exactly 3/7 of his pay left ove
maxonik [38]

Answer:

John receives a pay of $3,500.00

Step-by-step explanation:

x = John's pay

x = 1/2x + 250 + 3/7x     [1/2 = 7/14 and 3/7 = 6/14]

x = 13/14x + 250

x - 13/14x = 13/14x - 13/14x + 250    [1x = 14/14]

1/14x = 250   [multiply both sides by 14]

x = 3500

Check:

3500 = 1/2(3500) + 250 + 3/7(3500)

3500 = 1750 + 250 + 1500

3500 = 3500

Use the formula d=rt to find the distance a long distance runner can run at a rate of 9 1/2 miles per hour for time of 1 3/4 hou
eduard

d=rt

r = 9  1/2  as an improper fraction   (2*9 +1)/2 = 19/2

t = 1 3/4  as an improper fraction (4*1+3)/4 =7/4

d=rt

d = 19/2* 7/4 = 133/8
