Answer:
A
Step-by-step explanation:
To find the value you can just find 12% of each number (trial and error), until one of them gives you 90 as an answer:
A) 750
750 * 0.12 = 90
B) 1080
1080 * 0.12 = 129.6
C) 360
360 * 0.12 = 43.2
D) 1168
1168 * 0.12 = 140.16
This tells you that 90 is 12% of the 750, and that is why it is your answer
I hope this helps!
First, you combine like terms. I would start by circling the term and the sign in front of it. (A term is a piece separated by an addition/subtraction sign.) You can only combine terms with the same variable. 4.8a-2.1a-6.3b+7b is the same as your equation, just rearranged. Then, subtract (4.8a-2.1a) which is 2.7a. Add (-6.3b to 7b) The answer is 0.7b.
