Answer:
130 shark cookies
Step-by-step explanation:
Number of shark cookies sold last month = 65
Number of clown fish cookies sold last month = 85
Ratio = 
Now, the Marine Discovery Aquarium plans to order 170 clown fish cookies this month.
So,
Number of shark cookies : Number of clown fish cookies = 
Number of shark cookies : 170 =
Therefore,
Number of shark cookies = 
(20x^2-19x+3)/5x-1
(400x-19x+3)/5x-1
(381x+3)/5x-1
381x/5x-1 + 3/5x-1
(381/5-381) + (3/5x -3)
(76.2-381) + (3/5x -3)
304.8 + 3/5x-3
101.8 +3/5x
That's what I got. I'm not too sure if it helps though.
Answer:
Step-by-step explanation:
-7(x-3)
y-1+1=-7x+21
y=-7x+22
Let's write some equations.
Mingwei's distance from Town A after
hours from 8:00 is
.
Ali's distance from Town B after
hours is
, since he doesn't start walking for 40 minutes.
When Mingwei's distance is twice Ali's, they've met up (since their distance from Town A is twice their distance from Town B).
So, this gives
, so
, so
, so the time is 10:40.
After
hours, Mingwei has traveled
kilometers while Ali has traveled sixty, so the distance between the towns is
kilometers.
Once you combine it, you get 10w + 18
