Answer:
Step-by-step explanation:
10 diget number
Answer:
The reason why both have the same value is because you are only moving the decimal place. The difference between 51.2 and 5.12 is that you divided 10 from 51.2 to get 5.12. Same goes for 6.4 and 0.64.
51.2 / 6.4 = 8
5.12 / 0.64 = 8
Begin to isolate x by adding 23 on both sides of the equation
10x = 52 - 3x
Now, add 3x on both sides of the equation
13x = 52
Divide by 13 on both sides to isolate x
x = 4

Answer:
8
Step-by-step explanation:
let the number be n , then
n + 3 = n - 3 ( multiply through by 4 to clear the fraction )
n + 12 = 4n - 12 ( subtract 4n from both sides )
- 3n + 12 = - 12 ( subtract 12 from both sides )
- 3n = - 24 ( divide both sides by - 3 )
n = 8
That is the number is 8
