Answer:

Width = 3x                                         So,  

Length = x                                          3w + w = 56/2 = 28

3x + x = 4x                                              

56 / 4 = 14                                            w = 7

x = 14                                                    

14 x 3 = 42                                            

                                                         

Answer: 42 meters                                  Answer: dimension-  7 meters

The temperature in frostville was at 50*F at midnight,and it dropped at a constant rate for the next 10 hours.
bazaltina [42]

After 10 hours the temperature is shown on the graph as 30 degrees.

50 degrees - 30 degrees = 20 degrees.

The temperature dropped 20 degrees in 10 hours.

Divide the change by the time:

20 degrees / 10 hours = 2 degrees per hour.

Because the temperature dropped, the change would be negative.

The answer is D. -2 degrees per hour.

bazaltina [42]

Answer:

1st answer is in the pic

2nd answer is that there are

1650 childs and 550 adults

Step-by-step explanation: the picture

If you want the 1st answer in words, it is here

Correct result:

a =  100

c =  800

t =  300

Solution:

6a + 5t + 4c = 5300

a + t + c = 1200

(8/3)t = c

6•a + 5•t + 4•c = 5300

a + t + c = 1200

(8/3)•t = c

6a+4c+5t = 5300

a+c+t = 1200

3c-8t = 0

a = 100

c = 800

t = 300
