Answer:
3 3/5
Step-by-step explanation:
Raphel bought 2 1/2 pounds of chicken for $9
Therefore the cost per round of the chicken can be calculated as follows
9÷5/2
= 9×2/5
= 18/5
= 3 3/5
390-35=355
355-10w
355/10=35.5
355-10(35.5)
35 and a 1/2 weeks
36 weeks to have the full amount needed
Since videos are 3 dollars since 1 times 3 is 3, 3 times 15 would be 45 dollars worth of videos. So you could purchase 45 songs after buying 15 videos.
Answer:
-18x + 4
Step-by-step explanation:
-6(3x - (2/3))
Factor it out
-18x + 6(2/3)
-18x + 4
Answer:
Step-by-step explanation:
Let the rate of boat in still water be b and the speed of the current be c
- Speed downstream = b + c
- Speed upstream = b - c
<u>We got equations for time:</u>
- 108/(b - c) = 3 ⇒ b - c = 36
- 108/(b + c) = 2 ⇒ b + c = 54
<u>Add up the equations:</u>
- b - c + b + c = 36 + 54
- 2b = 90
- b = 45 km/h
<u>Then finding the values of c</u>
