Answer:

Step-by-step explanation:

5 and 7 are both common factors of 35 and 40

Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.

This leaves A and B. Looking at the equation the difference between the two are the + and -

Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer

12. I don’t know how to do it

Answer:

BC = 50

Step-by-step explanation:

I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol

Okay so...

You would do

1. 6y-16 = 4y+6

You would subtract 4 from 6...

2. 2y-16 = 6

You would then add 16 to 6...

3. 2y = 22

Then, divide 2 from 22...

4. y = 11

Substitute into BC...

5. 6 (11) - 16 = 66 - 16 = 50

Then, you get your final answer...

6. BC = 50

I hope it's right. Good luck ^^

Commutative property of addition is being used.

2 to 3 means that the ratio of romantic students has a numerator of 3. If there is a numerator of 3 the denominator has to be 5 because 2+3 is five if the fraction is 3/5, then the answer is A.
