Simplifying 6ab + 3ab - 7ab
so we can write it 
6ab + 3ab - 7ab = 0 ( because there is nothing on right side ) 
9ab - 7ab = 0
2ab = 0
So the coefficient of ab is 2.

Correct option is C.

To simply to expression 6ab+3ab-7ab, we do:
6ab+3ab-7ab+= (Just do regular addition and subtraction if they have the same coefficent)
9ab-7ab=
2ab
So the answer is C.

Korolek [52]

Answer:

x = 335 - (6 * v)

Step-by-step explanation:

In order to calculate the value remaining, we need to first multiply the daily cost of each visit by the number of visits made to the gym which is represented by the variable (v). Once we have this cost of all the days then we subtract this amount from the current account balance in order to get the new remaining balance which is represented by x.

x = 335 - (6 * v)
