Change them into improper fractions
and then find a common denominator, then minus, add, whatever for each one
You should use a bar graph because that would work better
Answer:
10x+2
Step-by-step explanation:
First we work on the paranthesis. We will times 5 and 2x to get 10x
and then we times 5 and 3/4 to get 3
So now we have 10x+3-1.75
Next, we subtract 3-1.75 which is 2
Lastly we look at the equation as a whole!
10x+2
