Letter D it’s incorrect, not sure tho
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. If you have any questions, you can message me!
Answer:
Step-by-step explanation: 800/x=100/17
(800/x)*x=(100/17)*x - we multiply both sides of the equation by x
800=5.88235294118*x - we divide both sides of the equation by (5.88235294118) to get x
800/5.88235294118=x
136=x
x=136
83% of 800=664
