Answer:

She swims for 3 hours each morning.

Step-by-step explanation:

To determine the number of hours that Kenny swims in the morning, it is necessary to perform the following equation, taking into account that he swims 5 days a week for a total of 30 hours a week, and that in the afternoon he swims for 3 hours:

X + 3 x 5 = 30

X + 3 = 30/5

X = 6 - 3

X = 3

Therefore, Kenny swims for 3 hours in the morning.

Answer:

The cost of comic is $2.8 and the cost of magazine is $4.2.    

Step-by-step explanation:

Given : Eugene bought 27 comics and 12 magazines for $126. If 3 comics cost  as much as 2 magazines.

To find : The cost of each comic ?

Solution :

Let the cost of a comic be 'c'

the cost of a magazine be 'm'

If 3 comics cost  as much as 2 magazines.

i.e. 3c=2m

c=\frac{2m}{3} ....(1)

Eugene bought 27 comics and 12 magazines for $126.

i.e. 27c+12m=126  .....(2)

Substitute the value of c from (1) in (2),

27(\frac{2m}{3})+12m=126

18m+12m=126

30m=126

m=\frac{126}{30}

m=4.2

Substitute in (1),

c=\frac{2(4.2)}{3}

c=\frac{8.4}{3}

c=2.8

So, The cost of comic is $2.8 and the cost of magazine is $4.2.
