Each individual contributed $x
3x=$19.50
x=$6.50
Each friend contributed $6.50
Answer:
E
Step-by-step explanation:
When you substitute (5,-19) for A you get -19=-21 which is incorrect, when you substitute it for B you get, -19=-13 which is also incorrect, for C you get -19=-14, D you get -19=-22, and finally for E you get the correct answer which is -19=-19. Hope this helps :)
Answer:

Step-by-step explanation:
In these two lines that intersect, we can see that 4 angles are opposite from each other. This means that they are vertical angles and therefore equal. 2 of these angles have values next to them, which happen to be across from each other.
Based on this, we know that they are equal. If we write this as an equation, we can solve it to find the value of x.
75º = (4x - 25)º
Add 25º to both sides of the equation
100º = 4x
Divide both sides of the equation by 4 to isolate x
x = 25

Answer:
(x,y)=(10,6)
Step-by-step explanation:
Substitute the value of x into the equation {4x+ 5= 70
{x= 6+ 2/3y
solve the equation 4(6+2/3y) +5y = 70
substitute the value of y into the equation y=6
solve the equation x=6 + 2/3 times 6
A possible solution is x= 10
Check the solution (x,y) = (10 ,6)
Simplify {4 times 10 + 5 times 6 =7
{3 times 10 - 2 times 6 = 18
The ordered pair is a solution {70 = 70
{18 =18
