Answer:
2.36
Step-by-step explanation:
It is subtraction between integers. For subtraction within positive and negative integers, you have to add the opposite.
To add the opposite, the first digit, a, (which happens to be a variable), remains the same. The second digit, - will be changed to +. The last digit, a number, which is -3.75, will be rewritten as 3.75, its integral opposite.
This is fairly similar to the keep-change-flip method used in fractions.
Now, let's put the problem together.
Our equation is now displayed as:
a - 3.75 = 6.11
The question is pretty straightforward from now on- To find out the variable a, we need to subtract 3.75 from 6.11, thus resulting in the answer of 2.36.
Hope this helped!
