The cost of beginner classes is $7.6 and the cost of the advanced classes is $29.2
What are the four basic algebraic operations?Addition, subtraction, multiplication, and division are the four basic algebraic operations.
Given that, x is the cost of beginner classes, and y is the cost of advanced classes.
The relationship between beginner classes and advanced classes is
x=0.5y-7
4x+3y=118
From the first equation, we can write
y=2x+14
Using this equation, we can write
4x+3(2x+14) =118
10x+42=118
i.e x=7.6
Substituting the value of x in the equation y=2x+14, we get
y=(2*7.6)+14
i.e y=29.2
The cost of beginner classes is $7.6, and the cost of advanced classes is $29.2.

On a coordinate grid, point P is at (5, 2) and point R is at (−3, −4). Points Q and S are a reflection of both points across the x-axis. What are the coordinates of Q and S? (5 points) a Q(−5, 2), S(3, −4) b Q(−5, −2), S(3, 4) c Q(5, −2), S(−3, 4) d Q(−5, 2), S(−3, 4)
Answer:
The correct option is;
c. Q(5, -2), S(-3, 4)
Step-by-step explanation:
In a reflection of a preimage across the x-axis of a point with coordinates (x, y), the value and sign of the x-coordinate of the image does not change while the value of the y-coordinate of the image is the same as the value of the y-coordinate of the pre-image, but with opposite sign
Therefore, we have
The coordinate of the preimage before the reflection across the x-axis = (x, y)
The coordinate of the image after the reflection across the x-axis = (x, -y)
Therefore, for the preimage point P(5, 2) before the reflection, we have the coordinate of the image point as Q(5, -2)
Similarly, or the preimage point R(-3, -4) before the reflection, we have the coordinate of the image point as S(-3, 4).
The correct option is therefore, Q(5, -2), S(-3, 4).

what percent of 12 is 40?
A. 0.25%
B. 4%
C. 25%
D. 40%
E. 400%
Answer:
25%
Step-by-step explanation:
If you would like to know what percent of 48 is 12, you can calculate this using the following steps:
x% of 48 is 12
x% * 48 = 12
x/100 * 48 = 12 /*100/48
x = 12 * 100 / 48
x = 25%
The correct result would be C. 25%.

a particle moves along the x-axis so that anytime t comma measured in seconds it's position is given by...
Given the position function s(t), you can get the acceleration function by differentiating s twice:
velocity = s'(t) = -5 sin(t ) + 3 cos(3t )
acceleration = s''(t) = -5 cos(t ) - 9 sin(3t )
Then when t = π, the particle's acceleration is
s''(π) = -5 cos(π) - 9 sin(3π)
… = -5 • (-1) - 9 • 0 = 5

And insurance agent receives 15% of the cost of each insurance policy she sells how much does the agent receive for a policy thst cost $300
In this question there are several important information's provided. Using these information's it is easy to get the answer to the question asked. Firstly it is already informed that the insurance agent gets a commission of 15% of the policy price for every policy sold. The agent sells a policy of $300.
Now we can write the equation as:
15% of $300 = [(15/100) * 300] dollars
= ( 15 * 3) dollars
= 45 dollars
So the agent gets a commission of $45 for selling a policy worth $300
Calcula la longitud en YARDAS de

y la longitud en
YARDAS de un trayecto B que mide 18.50
Answer:
Las longitudes solicitadas en yardas son:
Trayecto A = 109.361 yardas.Trayecto B = 20.231785 yardas.Step-by-step explanation:
Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:
1 metro = 1.09361 yardasCon ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:
Si:
1 metro = 1.09361 yardas100 metros = XEntonces:
[tex]x=\frac{100m *1.09361yardas}{1m}[/tex]Cancelamos metros y obtenemos:
x = 100 * 1.09361 yardasx = 109.361 yardasEn este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:
Si:
1 metro = 1.09361 yardas18.50 metros = XEntonces:
[tex]x = \frac{18.50m*1.09361yardas}{1m}[/tex]Cuando se cancelan los metros se obtiene:
x = 18.50 * 1.09361 yardasx = 20.231785 yardasAsí, el trayecto B en yardas corresponde a 20.231785 yardas.

Answer:A= 1,2 B=1,2 C=-9,10
Step-by-step explanation:
For A=

translate the triangle clockwise around the origin, (0,0), to put B' at (1,2)
For C= Translate point C to the left 4, and up 2, so the answer is (-9,10)
Gia opened two savings accounts at two diffrent banks. One account earns an annual 3.4% simple interest, and the other earns half as much. If she deposited $509 in each account, how much total interests will sh have earned in 3 years? A:$153.00 B:$38.25 C:$76.50 D:$51.00
Interest from first account is :
[tex]I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918[/tex]
Interest form second account is :
[tex]I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 = \$25.959[/tex]
So, total interest is :
[tex]I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877[/tex]
Therefore, total interest is $77.877 .

Which table represents a direct variation function?
Answer:
(A) First table
___________
Input: 6, 9, 12
Output: 8, 12, 16
Step-by-step explanation:
To determine whether or not a function is a direct variation, x and y must divide evenly and have a constant factor or factor that stays the same.
B and C don't divide evenly so those are already wrong, and D is wrong because x and y do not divide by the same factor every time.

The three angles of a triangle measure x+37, 90, and x+67. Find the measurement of the smallest angle in degrees.
Answer:
The smallest angle in the triangle is 30°
Step-by-step explanation:
You can solve this by including the fact that the sum of the angles in the triangle has to be 180 degrees. We're given values describing the angles, so we can simply add them together, say the equal 180, and solve for x:
[tex](x + 37) + 90 + (x + 67) = 180\\2x + 37 + 90 + 67 = 180\\2x + 194 = 180\\2x = 180 - 194\\2x = -14\\x = -7[/tex]
The smallest angle then is x + 37, or 37 - 7, giving us 30°
If three angles of a triangle measure x+37, 90, and x+67. Then 30 degrees is the measurement of the smallest angle in degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given,
The three angles of a triangle measure x+37, 90, and x+67.
We need to find the measurement of smaller angle.
From angle sum property we know that the sum of three angles is equal to 180 degrees.
x+37+90+x+67=180
2x+194=180
Subtract 194 from both sides
2x=180-194
2x=-14
Divide both sides by 2.
x=-7
Substitute the value of x in smallest angle
x+37
-7+37=30
Hence the measurement of the smallest angle in degrees is 30
