Answer:

6 for cherry

19 for blackberry

Step-by-step explanation:

Cherry = x

Blackberry = y

<u>Make system of equations:</u>

Castel:

13x + y = 97

Jasmine:

6x + 3y = 93

<u>Substitution w/ Castel's equation:</u>

y = 97 - 13x

<em>Put into Jasmine's equation</em>

6x + 3(97 - 13x) = 93

6x + 291 - 39x = 93

291 - 33x = 93

-33x = -198

x = 6 $ per Cherry Pie

<u>Plug x = 6 into any equation (choose Castel's):</u>

13(6) + y = 97

y + 78 = 97

y = 19 $ per Blackberry Pie

The correct answer is the 2nd choice because -1/6 is closer to 0 and the surface of the pool would be considered 0. -4/6 is farther away from 0 so it is less.

Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video?

she spends 4 hours on a 3 minute video
so there are 60 minutes in an hour
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video
3 divided by 240
3/240= 0.0125
so her constant rate is 0.0125 minutes an hour
so divide 9 minutes by her constant rate
9/0.0125 = 720
so she spends 720 minutes on a 9 minute video.
divide 720 by 60 since there are 60 minutes in an hour
720/60 = 12
so she spends 12 hours on a 9minute video
