Keta sold tickets for her school play at $6 for students, and $9 for adults. She sold 15 adult tickets and made a sales total of $315. How many student tickets were sold 48 points
Answer:
Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
x+ 2x = 315
3x = 315
and x = 105 (which is the number of tickets sold to adults

Write an equation of the line that passes through (−1, 3) and is perpendicular to the line y=1/9x−1.
Answer:
Step-by-step explanation:
General equation of line
y = mx + c
m is slope
y = (1/9)x - 1
1/9 is slope
Since the other line that passes through the point is perpendicular, the product of both slopes is -1
1/9 * m = -1
m = -9
Using point-slope method
y-y1 = m(x-x1)
y-3 = -9(x-(-1))
y-3 = -9(x + 1)
y-3 = -9x -9
y = -9x-6

The regional manager of a chain of department stores created the following stem and leaf plot showing the number of pairs of glasses at each of the stores how many department stores have exactly 37 pairs of glasses
Answer:
The stem and leaf plot is not shown, so I will answer the question in a general way.
Suppose you have the following stem and leaf plot
I 2 I 0 5 8
I 3 I 4 4 7 8
I 4 I 0
Then, the data is: 20, 25, 28, 34, 34, 37, 38, 40. In consequence, one department stores has exactly 37 pairs of glasses. But if your stem and leaf plot is:
I 2 I 0 5 8
I 3 I 7 7 7 8
I 4 I 0
then, three department stores have 37 pairs of glasses, and none of them have 34 pairs of glasses.

The value of which of these expressions is closest to e?
A. (1+1/19)^19
B. (1+1/22)^22
C. (1+1/20)^20
D. (1+1/21)^21
Answer:
B.
Step-by-step explanation:
Given: expressions
To find: the expression whose value is closest to e
Solution:
Value of e is 2.718
[tex]\left ( 1+\frac{1}{19} \right )^{19}=\left ( \frac{20}{19} \right )^{19}=2.65\\\left ( 1+\frac{1}{22} \right )^{22}=\left ( \frac{23}{22} \right )^{22}=2.659\\\left ( 1+\frac{1}{20} \right )^{20}=\left ( \frac{21}{20} \right )^{20}=2.653\\\left ( 1+\frac{1}{21} \right )^{21}=\left ( \frac{22}{21} \right )^{21}=2.656[/tex]
Therefore, value 2.659 is closest to the value of e.
So, option B. is correct.

Step-by-step explanation:
Anna takes 2 minutes to perform each exercise of her workout routine at the gym. She has already been at the gym for 20 minutes and wishes to be there no longer than 1 hour in total. Anna wonders if she has time to do 18 more exercises.
(1.) Write an inequality to find the maximum number of exercises x Anna can perform without leaving the gym later than she planned.
(2.) Does Anna have time to do 18 more exercises. Explain.
Answer:
1. 20 + 2x ≤ 60
2. Yes, see explanation
Step-by-step explanation:
Let x equal the amount of exercises Anna can perform.
The inequality will look like this:
20 + 2x ≤ 60
Let's go over each of the values and why there in the equation.
20: The amount of minutes Anna has already spent in the gym
2: The amount of minutes per exercise
x: The amount of exercises Anna can perform
≤: The amount of exercises must be less than or equal to the amount of time Anna is willing to spend in the gym.
60: The amount of minutes in an hour; the amount of time Anna is willing to spend at the gym.
Now, plug in 18 for x for question 2.
20 + 2(18) ≤ 60
Evaluating 2*18, the inequality becomes 20 + 36 ≤ 60.
Evaluating 20 + 36, the inequality becomes 56 ≤ 60.
Since 56 is less than 60, we can determine that Anna has time to do 18 more exercises.

Which graph represents the function f(x) =1/3 |x|?
Step-by-step explanation:
f(x) = 1/3|x|
then
f(x) = 1/3x , if x ≥ 0
and
f(x) = -1/3x , if x ≤ 0
the slope of f(x) = 1/3x is 1/3
the slope of f(x) = -1/3x is -1/3
this two above conditions apply on to the fourth graph to the right.

Answer:
x = 17°, m∠ A = 114°
Step-by-step explanation:
We can tell that these pair of angles are corresponding, provided;
Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,
m∠ A = m∠ B ⇒ Substitute values of A and B,
6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,
3x + 12 = 63 ⇒ Subtract 12 on either side of equation,
3x = 51 ⇒ Divide either side by 3,
x = 17 ⇒ Substitute value of x to solve for m∠ A,
m∠ A = 6 * ( 17 ) + 12,
m∠ A = 102 + 12,
m∠ A = 114
Solution; x = 17°, m∠ A = 114°
Answer:
x = 17, ∠A = 114°
Step-by-step explanation:
I'm 8 years old and I know how to do this.
6x + 12 = 3x + 63
3x + 12 = 63
3x = 51
x = 17
6(17) + 12
102 + 12 = 114

The perimeter of a rectangular swimming pool is represented by the expression 8x – 2. If the width of the swimming pool is represented by the expression x – 1, which expression represents the length of the pool? 7x – 1 6x – 4 3x 6x
Answer:
61 ft
Step-by-step explanation:
Answer:
The length of rectangle is 3x.
Step-by-step explanation:
Given that the perimeter of rectangle formula is P = 2l + 2w where l represents length and w is width. Then you have to substitute the expressions into the formula :
[tex]p = 2l + 2w[/tex]
Let p = 8x - 2,
Let w = x - 1,
[tex]8x - 2 = 2l + 2(x - 1)[/tex]
[tex]8x - 2 = 2l + 2x - 2[/tex]
Next you have to find the expression for length by moving all the unrelated terms to the other side :
[tex]8x - 2 - 2x + 2 = 2l[/tex]
[tex]2l = 6x[/tex]
[tex]l = 3x[/tex]

Mrs. Harless surveyed 18 students about the number of movies they watched this past summer. She displayed the results in a circle graph and a line graph. Which is the better display? Why?
The line graph is bettee.
The better display for the survey of 18 students about the number of movies they watched this past summer is a circle graph.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given that, Mrs. Harless surveyed 18 students about the number of movies they watched this past summer, she used a circle graph and a line graph.
Since, a line graph used to track changes over short and long periods of time, It represents the change in a quantity with respect to another quantity. It shows how the value of something changes over time, or compare how several things change.
Whereas, a circle graph helps organize and show data as a percentage of a whole, it is divided into slices to illustrate numerical proportion.
Therefore, if Mrs Harless used a circle graph, it would be better to understand the data of the students.
Hence, the better display for the survey of 18 students about the number of movies they watched this past summer is a circle graph.

Find the value of x and the value of y.
Answer:
B.
Step-by-step explanation:
If you extend the middle line, you will find that the two angles that the line makes are 60° and 40° by alternate interior angles.
Then, you can just make an equation:
2x + 2x - y + y + 60 + 40 = 360
4x = 260
x = 65°
Now you can use same side interior angles to make another equation:
2x - y + 60 = 180
130 + 60 - y = 180
y = 10
