Answer:
Step-by-step explanation:
If 70 is 50% then 140 is 100%.
c is 75% of 140 = 105

b is 100% of 140 =140
Steve didn't put the parenthesis when he went to the second part of the equation, instead of putting the parenthesis he skipped them and keep going along with the equation.
I don't know if you needed this but the answer to the math problem would be
Answer: 2 x
...............the answer is D
So, let's solve all of them and see:
a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers
a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers
a * (-b) = a * (-b) ⇒ negative answer no matter what
a / (-b) = a / (-b) ⇒ negative answer no matter what
So the answer is:
<em>"None of the above"</em>.
