There were 7/20 cup of chocolate chips left for cookies
I need the answer to that problem too.
<span>The first person can have any birthday. That gives him 365 possible birthdays out of 365 days, so the probability of the first person having the "right" birthday is 365/365, or 100%.The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%.</span>
Answer:
20 miles.
Explanation:
2x + 20 = 3x
x = miles driven
The left side of the equation represents Laguna's, and the right side Salvatori's.
You can multiply the miles driven by their price per mile. This gives you (2x) on the left, for Laguna's $2 per mile, and (3x) for Salvatori's $3 per mile.
The (+20) represents the initial payment for Laguna's, but Salvatori's doesn't have this, so we can leave it out.
Finally, eliminate.
Subtract 2x from 3x on the right. This leaves you with 20 = 1x.
