You have sold 72, and your friend has sold 74. Meaning your friend has sold 2 more magazine subscriptions than you.
Answer:
9/2
Step-by-step explanation:
4.5 = 4 1/2 = 9/2
Janine = J = 15
Leah = L = ?
L = J + 6
L = 15 + 6
L = 21
So Leah spent $21
1/2+1/2=2/2=1 so 1/2 was eaten and the other half was leftovers.
Answer:
72 parts
Steps:
Convert the 4 hours into minutes. There are 60 minutes in an hour. Therefore, 4 hours = 240 minutes.
Divide 240 minutes by 40 minutes. This equals 6. Therefore, the machinist can produce the 12 parts 6 times in 4 hours.
Finally, multiply the 12 parts by the 6 times he can produce. Therefore, the machinist can produce 72 parts in 4 hours.
