Asmall concert hall was setting up chairs for the next concert. the graph below shows the
number of total chairs setup depending on the number of rows. which of the following ratios correctly show the ratio of rows to chairs presented in the graph?
a. 3: 60
b. 4: 80
c. 5: 90
d. 2: 20
e. 1: 20

I believe it's A, sorry if it's incorrect. ^-^'

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
