Mr.willer needs 216 cans because 27 vans times 8 banks equals 216 and 23 times 9 equals 207 so he would need 9 more cans
Answer:
a=2
Step-by-step explanation:
3(3a+2)+6=30
9a+6+6=30
9a+12=30
9a=18
a=2
Total of 5 times = 48 + 48 + 49 + 46 + 64 = 255 mins
Goal:
Average = 53 mins
Total = 53 x 6 = 318 mins
6th ride = 318 - 255 = 63 mins
Answer: She needs to attain 63 mins for her 6th ride.
Answer:
Image B shows a reflection.
When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.
If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.
20 + 20 = 40
20 * 2 = 40
Serena will be 20, her mom will be 40.
