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
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!
Let's denote the number as "x". According to the given information, we have the equation:
3x - 5x = 3.7
Simplifying the equation:
-2x = 3.7
Dividing both sides of the equation by -2:
x = 3.7 / -2
So the number is approximately -1.85.
For the second part of your question, it is not clear what equation or problem you are referring to. Could you please provide more information or clarify your question?
To find the number, let's break down the given information into equations:
Let's assume the number is 'x'.
According to the problem, when the number is trebled (multiplied by 3), we get 3x.
And when five times the number is subtracted from this, we get: 3x - 5x.
The problem tells us that the result of this operation is 3.7. Therefore, we can set up the equation:
3x - 5x = 3.7
Combining like terms, we have:
-2x = 3.7
To find the value of 'x', we need to isolate it. We can do this by dividing both sides of the equation by -2:
-2x / -2 = 3.7 / -2
Simplifying further:
x = -1.85
So, the number is -1.85.
Now moving onto the next part of your question:
If the total answer is 1 whole number 17 over 20, we need to convert this mixed number into a fraction.
1 whole number is equivalent to the fraction 1/1, and when we add 17/20 to it, we can represent it as:
1 + 17/20
To combine the whole number and fraction, we need to find a common denominator. In this case, the common denominator is 20. Therefore:
1 + 17/20 = 20/20 + 17/20 = (20 + 17) / 20 = 37/20
So, the solution to the equation is 37/20.
