Step-by-step explanation:
It might be 21/30 , hope it helps though :)
5 quarters, 15 dimes
q + 10 = d
0.25q + 0.1d = 2.75
0.25q + 0.1(q + 10) = 2.75
0.25q + 0.1q + 1 = 2.75
0.35q = 1.75
q = 5
Check:
0.25(5)+ 0.1(15)= 2.75
1.25 + 1.5 = 2.75
2.75 = 2.75 :)
Hello!
You add the amount of sections have red or purple
2 + 2 = 4
Put this over the amount of sections
4 / 10 = 0.4
Multiply this by the amount of times he spins the spinner
180 * 0.4 = 72
The answer is about 72 times
Hope this helps!
