Answer:

  3 km

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW

Filling in the given information, we can solve for the length.

  1/4 = L·(1/12)

Multiplying by 12, we see that ...

  3 = L

The array is 3 kilometers long.

Christian sold tickets to the game . Good seats were $5 each and poor seats cost $2 each. 210 people attended and paid $660. How
Sholpan [36]
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)

5a + 2b = 660
-2a - 2a = -420

3a=240
a= 80
*3 people purchased good seats.

Now we can plug that number in

5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats

dexar [7]

Answer:

He worked a total of 5 hours.

Step-by-step explanation:

The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35.

35 = one hour.

35 + 23 = 2 hours .  =  58.

35  + 23 + 23 = 3 hours. =  81.

35 + 23 + 23 + 23 = 4 hours.  =  104.

35 + 23 + 23 + 23 + 23 = 5 hours. =  127.

We were looking for if the man earned $127 dollars how many hours would be be working.


He'd be working 5 hours.

Hope this helps (:
