Since there’s 3 green and 4 yellow that adds up to 7 and with only 3 marbles left that is 3:10 and that make the probability 30% or 0.30
Let, the number = x
Then, x + 72/x = -17
x² + 72 = -17x
x² + 17x + 72 = 0
x² + 8x + 9x + 72 = 0
x(x + 8) 9(x + 8) = 0
(x + 8)(x + 9) = 0
x = -8 OR -9
In short, Your Number would be: Either -9 or -8
Hope this helps!

Answer:
$ 12.6 / h
Step-by-step explanation:
5% of 12 = 0.05 * 12 = 0.6
Now adding it to the amount he makes, since it is a raise:
0.6 + 12 = 12.6 $ / h
Another (and faster) way to calculate it:
1.05 * 12 = 12.6
