For this case we have to by definition, if "y" varies directly with "x" then it is true that:
Where:
k: Is the constant of proportionality
We find the constant "k" according to the given data:
Thus, the constant of proportionality is 
Now, we find the value of "y" when 
Thus, when
, the value of y is 21.

Answer:
40
Step-by-step explanation:
X(amount of people)
Y(Total amount made)
Y/X=40
Chad plus his other 5 friends makes 6 people.
Y/6=40
*6 *6
Y=240
The money would be split evenly.
Z(Amount each person needs to make)
240/60=Z
40=Z
They each need to make 40, which makes sense because they would be earning the amount they make.
2 x 3 - (2-10) + (2 x 4) =
6 - (-8) + 8
6 + 8 + 8 = 22
So the answer would be g, 22.

Answer:</h3><h3>
156in²</h3>
Step-by-step explanation:
Area of the border = Length * Breadth
If the outside measures 10in by 11in with 1-in border, the length of the picture with border = 10+(1+1) * 11+(1+1)
Area of the border = 12*13
Area of the border = 156in²
Note that the border length will be added at both edges of the frames for each length and the width of the frame
Answer:
Step-by-step explanation:
This function actually has two solutions in the given interval, at {5, 7}; at both of these x-values, the function value is 1.
