At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The number of food tickets sold was 10 less than twice the number of ride tickets sold.The system of equations represents x, the number of food tickets sold, and y, the number of ride tickets sold.
2x + 3y = 1240
x = 2y – 10
How many of each type of ticket were sold?
Answers
Answer:
Here, x represents the umber of food tickets sold and y represents the number of ride tickets sold.
Given the system of equations:
....[1]
....[2]
Substitute the equation [2] into [1] we have;
Using distributive property,
Combine like terms;
Add 20 to both sides we have;
Divide both sides by 7 we have;
y = 180
Substitute this in [2] we have;
therefore, each type of ticket were sold are:
the number of food tickets sold is, 350 and the number of ride tickets sold is, 180
7y-20=1240
7y=1260
y=180
2x+3(180)=1240
2x+540=1240
2x=700
x=350
So they sold 350 food tickets and 180 ride tickets in total.

if QT is an altitude of triangle QRS
then
the measure of angle QTS is equal to 90°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13
the answer is

2y=-6x+8
First, the slope of any equation, is always the coefficient with the variable "x".
So, the slope for this line, is -6x.
To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.
2y=-6x+8
2
y=-3+4
Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.
And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to 1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.
The answer is 2) 1/3.
