Answer:
B.)
Step-by-step explanation:
In step #1 they did the distributive property
2/5 × 15x = 6x
2/5 × -30y = -12y
The new equation would be:
6x - 12y + 10x
<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>
They then combined 6x + 10x to get 16x
16x - 12y
They then factored it out to 4(4x - 3y)
If she would use it 150 times, the expected amount would be 60 times for it to land on yellow or green
