3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
Hello!
In a function, each input must have only one output. Outputs can have multiple inputs, but each input must have one output. For example, {(4,-1), (4,-2)<span>} is not a function, as 4 has two outputs.
In B, -2 has two outputs, 3 and 1, so it is not the answer.
In C, 3 has two outputs, 5 and 2, so it is not a function.
In D,-1 has two outputs, 1 and 5, so it will not work.
In A, each number has one output, so it is a function.
I hope this helps!</span>
Here where you label the y and slope
Answer:
Line FN.
Step-by-step explanation:
A chord is a line whose endpoints both lie on the circle.
All the other lines' endpoints are on the circle.
In line FN, point N is on the circle but point F is not.
This makes line FN not a chord.
Ok so, it all depends if Shane is likely to jump win over all of the other seventh graders then the eighth graders should earn the 50 points...
But if the roles are reversed the the Seventh graders should earn the 50 points.
There is not a full answer to what I am saying but from speculation you should be able to decide..
