Answer:

Step-by-step explanation:
First, distribute the -2 to the rest of the parenthesis, following PEMDAS.

Then, add -6a to both sides.

Now, you can divide both sides by 2 to isolate b.

Divide to simplify.

I think you just multiply the amount of pennies for one grooming job by 9
Using the function concept, it is found that f is a function, as each student is related to only one GPA and only one number of credits.
In a function, <u>one value of the input can be related to only one value of the output</u>.
In this problem:
- The input is the student.
- The output is the student GPA, and the number of credits earned.
Each student is related to only one GPA and only one number of credits, hence <u>one value of the input is related to only one value of the output</u>, and f is a function.

We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a
1 metric ton = 1,000 kilograms
To convert from kilograms to metric tons, divide by 1,000.
10,600÷1,000=10.6 metric tons
