Answer: 
Step-by-step explanation:
You need to remember the mulplication of signs:

Knowing this, you can distributive the negative sign. Then you get:

Now you need to add the like terms. Then:

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

Subtracting .5 pounds from 11 leads you with 10.5 divide that by 4 to get the weight of each notebook, 2.625
The value of c is 233.3
Step-by-step explanation:
Given equation is:

To find the value of c, we have to isolate c on one side of the equation
So,
Adding 250 on both sides

Multiplying by 20 on both sides

Dividing both sides by 18

Rounding off to the nearest one decimal place
c=233.3
The value of c is 233.3
