Question

the sum of two numbers is 25.one of the number exceeds by other by 9.the numbers are _ and_​

Answer 1

Answer:

8 and 17

Step-by-step explanation:

Let the smaller number be x

Since the greater number exceeds the lesser number by 9, its value will be x+9

The sum of these two numbers is 25, so:

x + (x+9) = 25

2x + 9 = 25

2x = 25 - 9 = 16

x = 16/2 = 8

x is 8 so x+9 will be 8+9, which is 17

Answer 2

Answer:

x and x+9 are the numbers

x+x+9=25

2x+9=25

2x=25-9

2x=16

x=16/2

x=8

x+9=8+9=17

8 and 17 are the numbers

 

if you are not in algebra, here is another solution:

25/2=12.5

12+13=25

11+14=25

10+15=25

9+16=25

8+17=25  answer

you can do this because 25 is a small number and trial and error, although not the best strategy, is a mathematical strategy that you can use
