Hue is arranging chairs. She can form 2 rows of a given length with 1 chair left over, or 8 rows of that same length if she gets 11 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.
What is the equation and how many chairs are in each row?

(2x + 1) + 11 = 8x

2 chairs

Step-by-step explanation:

N: no. of chairs

x: no. of seats in 1 row

(2x + 1) + 11 = 8x

2x + 12 = 8x

6x = 12

x = 2

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
