$30, because basically, it's -100, +100, -30.
Answer:
7 Hours
Step-by-step explanation:
Given The lawyer charges $100 per month for a client.
Also he charges $75 per hour
Let the hours he worked for the client be x
The money the lawyer gets from the hourly charges is $75x
The total money the lawyer charged is $625
total money = monthly charges + hourly charges
625=100 + 75x
75x=525
x=525/75=7
Therefore the lawyer has to work for 7 hours to charge $625
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!
I'm guessing this is a slope problem, so the equation would be like this: y = mx + b where m is the slope and b is the y-intercept.

Using this,

Which is equal to,
