Step-by-step explanation:
It's a matter of units conversion. The conversion factors all have a value of 1 (the numerator is equal to the denominator), and all are chosen to cancel units you don't want and give units you do want.
The answer to this expression is 40. Why? Well, we can use PEMDAS in this expression.
P: Parenthesis
So this is our first step:
28 / 4 = 7
Next step: Simplify.
7 + 3 + 6 x 5
Then: E stands for Exponents but we have none so we can move on.
M stands for Multiply so we have our next step:
6 x 5 = 30
Now: Simplify.
7 + 3 + 30
Now that we have a simple equation, we can add the values to get our answer.
7 + 3 = 10
10 + 30 = 40
Therefore, your answer is 40. Whenever you see problems like this, be sure to use PEMDAS for a faster and more accurate evaluation.
Your final answer: 40.
