Answer:
C= 39
Step-by-step explanation:
lets call the children, c, and call adult, a,
c+a= 52 eq 1: a=52-c
c=3a eq 2
take a's value from eq 1 and plug it into eq 2
c=3(52-c)
c=156-3c
4c=156
c=39 the number of children that attended the ball game.
The student council has decided to have a raffle at the carnival. They came up with a table to show the relationship between the number of tickets bought and the number of raffle entries. Explain why it could be helpful for the student council to determine an equation to represent this data.
Answer:
An equation is helpful in other to make predictions about the number of raffle entries for a given number of tickets purchased.
Representing data such the one described above as an equation is helpful in other to obtain a mathematical model to make projection about the number of raffle entries possible for any number of ticket purchased.
For instance :
If the number of tickets bought = x
Number of raffle entries = y
A linear equation model to predict the number of raffle entries, y can be obtained. Hence, we can have a model in the form :
y = bx + c
Where, b = slope or rate of change
c = intercept.
An equation is helpful in other to make predictions about the number of raffle entries for a given number of tickets purchased.
Step-by-step explanation:
Answer:Write an equation to find the number of each type of ticket they should sell.Let "x" be # of adult tickets; Let "y" be # of student tickets: Value Equation: 5x+3y=450-------------------------- b. Graph your equation.y = (-5/3)x+150
c. Use your graph to find two different combinations of tickets sold.I'll leave that to you.
And so looking at a table only gives you a small number of data points, whereas an equation can be used to find any data point.

Write an equation in point-slope form for the line that passes through each point.
(-2, 11), vertical line
Answer:
You can't make a point=slope form equation.
Step-by-step explanation:
The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.

Answer:
99.75 square feet.
Step-by-step explanation:
First we would find the area of both shapes.
rear = 12.5
distance from back and front is 9.5.
to find the area of the rectangle, you'll need to do 12.5 x 9.5
= 118.75.
Then you'd find the area of the triangles;
BH/2.
4 x 9.5. = 38. divided by 2,
= 19.
than you subtract them,
118.75 - 19 = 99.75.
I hope this helps :)....

Miranda has been offered two jobs. The pay at job A would be $750 per month plus 15% of the value of the merchandise she sells. Job B offers $675 per month plus 20% of the value of the merchandise she sells. What value of merchandise must she sell in order to make more money at job B than job A? Which of the following best represents this situation?
A. 750 + 0.15x = 675 + 0.20x
B. 750 + 0.20x = 675 + 0.15x
C. 750 + 0.15x > 675 + 0.20x
D. 750 + 0.15x < 675 + 0.20x
Answer:
x - would be the total value of merchandise sold
y - would be her take home pay would be
Job A: y = 0.15x + 750
Job B: y = 0.20x + 675
We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x
0.20x + 675 > 0.15x + 750
0.20x - 0.15x > 750 - 675
0.05x > 75
x > 75/0.05
x > 1500
Miranda must sell more than $1500 worth of merchandise to have

Cole took a total of 36 quizzes over the course of 4 weeks. How many weeks of school will Cole have to attend this quarter before he will have taken a total of 45 quizzes? Assume the relationship is directly proportional.
Answer: 5 weeks
Step-by-step explanation: 36 / 4 = 9. This means in 1 week he finishes 9 quizzes. 9 x 5 = 45, therefore it would take him 5 weeks to finish 45 quizzes.
