Hamburgers cost $3 and hotdogs cost $2. The total cost of buying b hamburgers and d hotdogs can be expressed by C=3b+2d. How can
Temka [501]
C = 3b+2d is the same as 3b+2d = C

Let's isolate d. To do this, we first need to subtract 3b from both sides

3b+2d = C
3b+2d-3b = C-3b
2d = C-3b

Then divide both sides by 2

2d = C-3b
2d/2 = (C-3b)/2
d = (C-3b)/2

Take note of the parenthesis as they are very important. We want to divide ALL of C-3b over 2. We don't want to just divide -3b over 2.

The answer choices you have aren't 100% clear but I have a feeling your teacher meant to say d = (C-3b)/2 instead of d = C-3b/2 for choice A

If that assumption is correct, then the answer is choice A.

A 12 ounce can of store brand tomato paste costs $1.46 at a supermarket. The unit price of the sauce is listed on the shelf belo
kykrilka [37]
You can calculate it by divided but most of the people get confused about is it gonna be 12/1.46 or 1.46/12. The correct is 1.46/12 because take the money divided all 12 to get a unit price if you take 12/1.46 which mean divided all ounce can to money and that makes nonsense.


So 1.46/12 = $0.12 for each ounce can

Hope this help!

State the independent variable and dependent variable and find the slope.
Rudik [331]
Time is your independent variable, and snowfall is your dependent variable.

Slope can be found by calculating ∆y/∆x:
x =  \frac{0.06 - 0.02}{3 - 1}  \\ x =   \frac{0.04}{2}  \\ x = 0.02

Snowfall will accumulate 0.02 m every hour.
