Help me please. Thank you so much :’)

a.

Step-by-step explanation:

So let’s say a=1 and b=1 so then 1*1=2 (So 2=c) so in conclusion c/b (or 2/1) equals a (1) which would be the a (1). You can plug in any number into the equation (a*b=c) and (c/b=a) and it will always get the same answer. As long as you use the same numbers for a, b, and c. I really hope this helps.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
