Answer:
60 child tickets and 72 adult tickets
Step-by-step explanation:
Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60, y =72
Answer:
I believe the correct options are 1, 4, and 5.
Answer:28 green and 35 red
Step-by-step explanation:
Given
If there are r red counter and g green counter then
Probability of drawing a green counter is 
and 
Thus 



Also if 4 red and 2 green counter is added the probability of drawing a green counter is





Substitute the value of g in equation (ii)[/tex]



Therefore 
Thus there 28 green counter and 35 red counter
I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct
