A high school drama department sold 238 tickets for their performance.
o   An adult ticket cost $6.75.
o   A student ticket cost $3.50.
o   The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold? 

Answers

Let x = number of student tickets
Ley y = number of nonstudent tickets

then we know that the total number of tickets is 537

so

x + y = 537

if we multiply the cost of a ticket by the number of tickets we can also get the total $

3.2x + 5.9y = 2185.5

now we have two equations and two unknowns and we can find the value for these unknowns

lets use substitution

x + y = 537 that means that x = 537-y

substitute this value in the second equation

3.2(537-y) + 5.9y = 2185.5

1718.4 - 3.2y +5.9y = 2185.5

1718.4 + 2.7y = 2185.5

2.7y = 2185.5 - 1718.4

2.7y = 467.1

y = 173

x + y =537

x + 173 = 537

x = 364

Answer:

$6.75 + $3.50 = X

X ÷ $1,252.25

Step-by-step explanation:

$6.75 + $3.50 = $10.25

$10.25 ÷ $1,252.25 = 0.00818526652

The equation of the line is y=-1/2x-3.5

Step-by-step explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].

[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

[tex]-4=\frac{-1}{2} (1)+b[/tex]

[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex]    add both sides by 1/2 so that b is alone

[tex]\frac{-7}{2} =b[/tex]              

You can rewrite -7/2 as -3.5.

Jasmine began completing the table below to represent a particular linear function.

a. Complete the table and find the rate of change for the function

Rate of change:

b. Create a graph and write an equation to represent this function

Answers

Answer:

Step-by-step explanation:

Rate of change = Slope of line

Use the coordinates of two points to find the slope of the line.

Slope of line through (2,5) and (0,1) = (5-1)/(2-0) = 2

(0,1) is a point on the line, so the y-intercept is 1.

Slope-intercept equation of the line: y = 2x+1

Use the equation to fill in the rest of the table:

x = -2, y = -3

x = ½, y = 2

x = 1, y = 3

x = 3, y = 7

Answers

we want to follow PEMDAS
we will start with parentheses
31-19 = 12
So now we have 12 x 2 + 10
We then want to multiply
12 x 2 = 24

24 + 10
So our final answer is 34
31-19=12 12x2=24 24+10 = 34 . remember pemdas

A ranch hand herded his cattle to some grazing land. Then he began riding back to the ranch,
which is due west, at 7 miles per hour. Simultaneously, the cows began moving away from
him, too, headed due east at 3 miles per hour. How long did it take for the herd and the
ranch hand to be 2 miles apart? (Please help me !!)

Answers

Answer:

1/5 hr or 12 min

Step-by-step explanation:

We are going to use the formula D = RT

Let t = the time for  them to be 2 mi. apart

Then 7t = the distance the ranch hand traveled

and 3t = the distance the cows traveled

Since they traveled in opposite directions, the sum of their distances will give us how far they are apart.

So, 7t + 3t = 2

10t = 2

t = 2/10 = 1/5 hr. =  12 min.

Heather is a software saleswoman. her base salary is 1900, and she makes an additional $40 for every copy of math is fun she sells.
let P represent her total pay (in dollars) and N represent the number of copies of math is fun she sells. write and equation relating P to N and use this equation to find her total pay if she sells 27 copies of math is fun. ​

Answers

Answer:

[tex]P = 1900 + 40N[/tex]

[tex]P = 2980[/tex] when N = 27

Step-by-step explanation:

Given

[tex]Base\ Salary = 1900[/tex]

[tex]Additional = 40[/tex] per copy

Solving (a): Her total pay (P)

This is represented by:

[tex]P = Base\ Salary + Additional * N[/tex]

[tex]P = 1900 + 40 * N[/tex]

[tex]P = 1900 + 40N[/tex]

Solving (b): Total pay when N = 27

Substitute 27 for N

[tex]P = 1900 + 40 * 27[/tex]

[tex]P = 1900 + 1080[/tex]

[tex]P = 2980[/tex]

The basketball coach spent $35 on 5 t shirts for his team last season. This season, he needs to purchase 7 t shirts. If he pays the same rate as last year, how much will the t shirts cost?

Answers

Answer:

5 dollars

Step-by-step explanation:

last year he got 5 they were 7 dollars because 7x5 is 35 so do the same thing to do other it also equals 35

ok so he bought 5 last season and spent 35 last time. we first need to find how many each was for last season. we can do this by dividing 35 and 5.

so 35/5

is 7

the next season he needs to have 7,

2 more then the prior season.

we now know each t shirt is the same price as last season it’ll be $7 each.

so you’d multiply 7x7 which is

$49

final answer: $49
