The first thing we must do for this case is to define variables:
p = total number of paperclips
x = paper clips added by carmen.
The equation that models this situation is:
p = x + 37
Answer:
An equation that models the total number of paperclips in the box is:
p = x + 37
You multiply 12x8.3 and get the answer 100

Step-by-step explanation:
Probability=
Probability for a randomly chosen girl to be senior=
Probability for a randomly chosen girl to be senior=
Probability for a randomly chosen boy to be senior=
Probability for a randomly chosen girl to be senior=
For two independent events,
Probability for both event 1 and event 2 to take place=
Since choosing boys and girls is independent,
Probability for both boy an girl chosen to be senior=
Probability for both boy and girl chosen to be senior=
So,required probability is 
Step-by-step explanation:
-7(-4p+1) + 2p
-7 x -4 = 28p
-7 x 1 = -7
28p + 2p = 30p
so
30p-7
The answer would be it has one solution
