Answer:

x=10/3, y=14/3. (10/3, 14/3).

Step-by-step explanation:

2x+2y=16

10x-2y=24

---------------

x+y=8

10x-2y=24

-----------------

x=8-y

10(8-y)-2y=24

80-10y-2y=24

80-12y=24

12y=80-24

12y=56

y=56/12=14/3

x=8-14/3=24/3-14/3=10/3

x=10/3, y=14/3.

castortr0y [4]

Answer:

Answers are 3 AM ; 10 , 54

Step-by-step explanation:

We are given a graph.

Recording of temperature starts from 9 PM.

So from Graph,

Temperature ate 9 PM = 59°F

Temperature ate 11 PM = 54°F

Temperature ate 1 AM = 51°F

Temperature ate 3 AM = 50°F

Temperature ate 5 AM = 51°F

Temperature ate 7 AM = 54°F

Temperature ate 9 AM = 59°F

So, At 3 AM the water is at its lowest temperature.

and

After 10 hours passed, the temperature of the lake is 54°F.

Therefore, Answers are 3 AM ; 10 , 54
