4 rolls of yellow ribbon.

Step-by-step explanation:

2 x 9 = 18

4 x 1 = 4

18 + 4 = 22

Answer 2

Answer:

$total \: number \: of \: rolls = 6 \\ number \: of \: rollsof \: \: green = x \\ number \: of \: rolls \: of \: yellow = 6 - x \\ then \: \\ x \times 9 + (6 - x) \times 1 = 22 \\ 9x + 6 - x = 22 \\ 8x + 6 = 22 \\ 8x = 22 - 6 \\ 8x = 16\\ x = \frac{16}{8} \\x = 2\\then \: number \: of \: green \: = x = 2 \\ number \: of \: yellow = 6 - x = 6 - 2 = 4 \\ thank \: you$
