My son takes trumpet lessons. He has a choice of plans. Plan A requires that he pay a $210 annual fee and then pay $10 for a lesson. Plan B does not have a fee, but you pay $25 for a lesson. Write an equation to find out for how many lessons Plan A would equal Plan B if x = number of lessons?
Answer:
10x + 210 = 25x
Step-by-step explanation:
Plan A
Annual fee = $210
Payment per lesson = $10
If 'x' lessons to be taken, total cost = 10x + 210
Plan B
Annual fee = 0
Payment per lesson = $25
Total cost for 'x' lessons = $25x
Equation for the equal payments in both the plans for 'x' lessons,
10x + 210 = 25x

A number, x, is 4 times another number, y. The difference
between the two numbers is 18. What is the value of the
larger number?
Answer:
The value of the larger number is
[tex]x=24[/tex]
Step-by-step explanation:
A number, x, is 4 times another number, y.
[tex]x=4y[/tex] --------- (1)
The difference between the two numbers is 18.
[tex]x-y=18[/tex] -------(2)
Re-arranging equation (2) yields
[tex]-y=18-x\\y=x-18[/tex]------------- (3)
Substitute y=x-18 in equation (1)
[tex]x=4 (x-18)[/tex]
[tex]x=4x-72\\x-4x=-72[/tex]
[tex]-3x=-72\\x=\frac{72}{3}\\x=24[/tex]
Substitute x=24 in equation (3)
[tex]y=24-18\\y=6[/tex]

which linear inequality is represented by the graph? O y<2/3x+3 (A)
O y>3/2x+3 (B)
O y>2/3x+3 (C)
O y<3/2x+3 (D)
Answer:
C y>2/3x+3
Step-by-step explanation:
Use y=mx+b format. The B is the y-intercept. From the y-intercept (3), go up two then to the right 3. That gives you the slope, or mx which is 2/3. The area shaded is above so it would be the greater than symbol.

Given △ABC with coordinates A(1, 3), B(4, 5), and C(5, 2), what are the coordinates of △AʹBʹCʹ after the glide reflection described by T⟨−1, 1⟩° Ry-axis?
Answer:
A' = ( 0,4 )
B' = ( -3,6 )
C' = ( -4,3 )
Step-by-step explanation:
Transformation involves changing the coordinates of a shape.
The coordinates of △ABC after the glide transformation are [tex]A' = ( 0,4 )[/tex], [tex]B' = ( -3,6 )[/tex] and [tex]C' = ( -4,3 )[/tex]
The coordinates of triangle ABC is given as:
[tex]A = (1,3)[/tex]
[tex]B = (4,5)[/tex]
[tex]C = (5,2)[/tex]
The glide reflection is given as: T⟨−1, 1⟩° Ry-axis
So, we start by translating the shape by (x - 1, y + 1).
The coordinate ABC becomes
[tex]A = (1 - 1, 3 + 1) = (0,4)[/tex]
[tex]B = (4 - 1, 5 + 1) = (3,6)[/tex]
[tex]C = (5 - 1, 2 + 1) = (4,3)[/tex]
Next, we reflect the coordinates across the y-axis.
The rule of this reflection is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex]A' = ( 0,4 )[/tex]
[tex]B' = ( -3,6 )[/tex]
[tex]C' = ( -4,3 )[/tex]

Given:
[tex]OA=3[/tex] units
[tex]OA'=9[/tex] units
To find:
The scale factor of the dilation.
Solution:
From the given figure it is clear that the center of dilation is point O. Point A' is the image of point A. So,
[tex]\text{Scale factor}=\dfrac{OA'}{OA}[/tex]
Putting the given values, we get
[tex]\text{Scale factor}=\dfrac{9}{3}[/tex]
[tex]\text{Scale factor}=3[/tex]
Therefore, the scale factor of the dilation is 3.

Answer:
140
Step-by-step explanation:
7- Cranberry
2:Grape = 40 so 40/2 = 1
3:Pineapple
1= 20 juices
7+2+3 is 12
20 x 12 is 140

Step-by-step explanation:
Classroom A has n students.
Since Classroom B has 4 less students, they have (n - 4) students.
Also Classroom C has double the students in B, so they have 2(n - 4) students.
We have A + B + C = 40.
=> n + (n - 4) + 2(n - 4) = 40
=> n + n - 4 + 2n - 8 = 40
=> 4n - 12 = 40
=> 4n = 52, n = 13.
Hence there are 13 students in Classroom A.

Skyla wants to buy a massage table to start her spa business. She sees one she wants for $1,200. If she can save $13 a week, how many weeks will it take her to save up for the massage table?
Answer:
27 because you have to multipli and then divide
Answer:
about 93 weeks
Step-by-step explanation:
divide 1200 by 13 to get your answer which is 92.3076923077 so then you just instead of rounding to 92 you would round to 93 because it would take her more then 92 weeks so the answer would be about 93 weeks

Answer: x = 4 and y = -3
Step-by-step explanation:
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.
3(-2 -2y) + 5y = -3
-6 - 6y + 5y = -3
-y = 3
y = -3
Now that we know y, we plug it into the original equation and solve for x.
2x + 4(-3) = -4
2x + -12 = -4
2x = 8
x = 4
You can check the answer by plugging both x and y into either of the original equations.

At the beginning of a population study, a city had 320,000 people. Each year since, the population has grown by 4.8%. Let t be the number of years since start of the study. Let y be the city's population. Write an exponential function showing the relationship between y and t.
Answer:
y = 320,000 ( 1.048 ) ^x
x = number of years
(the ^ before the x symbolizes "to the power of," but I can't do that on my keyboard)
Step-by-step explanation:
formula i used:
A = amount that you start with
t = amount of years / time
%increase: you must convert your percent (4.8%) to a decimal (0.048)
A ( 1 + %increase ) ^t
Answer:
y = 320,000(1.048)^t
Step-by-step explanation:
4.8% = 0.048.
The population grows by 1.048 per year.
The required equation is:
y = 320,000(1.048)^t
