We are starting with 8+4+7+5=24 marbles. We're taking out 8, so we'll be left with 24-8=16 marbles. Think about those 16. If the probability of drawing a white one is 1 in 4, that means that 1/4 of the marbles are white. 1/4 of 16 is 16/4 = 4 marbles are white. Since we started with 8 white, and there are 4 left, we must have taken out 8-4 = 4 white marbles.
Answer:
an = 50 + (n - 1)150
Step-by-step explanation:
There are 12 inches in a foot.
Divide 94 by 12.
94 / 12 = 7.8333
So there are 7 feet and a few inches.
Now we multiply 12 to 7.
12 * 7 = 84
Subtract this from 94.
94 - 84 = 10
So there are 7 feet and 10 inches in 94 inches.
