When a number is trebled and five times the number is substrated, the result is 3.7, what is the number?and if total answer is 1 whole number 17 over 20 what is the solving

Answer 1

Let's call the number "x".
According to the given information, when the number is trebled (multiplied by 3), we get 3x.
And when five times the number is subtracted from this result, we get 3x - 5x = -2x.
Therefore, the equation becomes: -2x = 3.7

To solve for x:
-2x = 3.7
Divide both sides of the equation by -2:
x = -3.7 / -2
x = 1.85

So, the number is 1.85.

Regarding the second part of your question, if the total answer is 1 whole number 17 over 20, it means the number is 1 and 17/20.
Hope this helps!
