To find FDH and FDE you first need to solve GDH.
Here’s how to set up GDH.
8x-1=6x+15
Subtract 6x from both sides so that it cancels out.
2x-1=15
Add 1 to both sides so that it cancels out.
2x=16
Divide by 2z
x=8
Plug in.
GDH: 8(8)-1+6(8)+15=78
FDH: 122+78= 200
FDE: 122+15=137

Step-by-step explanation:
Answer:
- Melissa: 30
- Ryan: 23
- Chau: 69
Step-by-step explanation:
Let r represent the number of messages Ryan sent. Then Chau sent 3r and Melissa sent r+7. Their total was ...
(r+7) +(r) +(3r) = 122
5r +7 = 122 . . . . . collect terms
5r = 115 . . . . . . . . subtract 7
r = 23 . . . . . . . . . . divide by 5
Ryan sent 23, Melissa sent 30, and Chau sent 69 text messages.
Answer: why?
Step-by-step explanation:
According to the FIFO method, the earliest sweaters are the ones that are sold off first, so if we have 24 remaining, 15 were bought in September (at $45 each) and the last 9 were from June (at $38 each). Then we calculate the total value by:
15($45) + 9($38) = $1,017
The value of the inventory is $1,017.
