If we spin the spinner 10 times, what is the best prediction possible for the number of times it will land on yellow or purple?
kiruha [24]

Answer:

Yellow = 5 times and I think you meant blue since there is no purple so blue = 3 times

Step-by-step explanation:

There is ten in all and half of the spaces are yellow, or 50%. Out of ten times, you should land on it about half, or 5. For blue, there are 3 spaces, or 30%. Out of ten times, you should lamd on it about three.

3n-8+2(5n+3)=8n+5+4n
DaniilM [7]
<span>3n-8+2(5n+3)=8n+5+4n first I will do the multiplication
3n-8+10n+6=8n+5+4n Now I will simplify
13n -2 = 12n +5 Now I will add 2 to both sides
13n = 12n + 7 then I subtract 12n from both sides
n = 7</span>
