A dance academy charges $24 per class and a one time registration fee of $15. A student paid a total of $687 to the academy. Find the number of classes the student took.
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Question in the image below:
Answer:
x = 5/33 or 0.151515151
Step-by-step explanation:
7(-6x-2) = 8(3x-4)
step 1: simplify the equation.
-42x - 14 = 24x - 4
step 2: isolate the variable (using the balance method).
-42x - 14 + 14 = 24x - 4 + 14
-42x = 24x + 10
-42x - 24x = 24x - 24x + 10
-66x = 10
step 3: solve for x.
x = 10 ÷ -66
x = 5/33
Someone please help im stuck on this question
Step-by-step explanation:
x = 4.13636363
100x = 413.636363
100x - x = 413.636363 - 4 .13636363
99x = 409.5
x = 409.5 / 99
Answer:
[tex]\frac{91}{22}[/tex]
Step-by-step explanation:
Given: 4.1363636...
Let x=4.1363636...
We can see number 36 ( 2 digit repeating ) so we will multiply it by 100
On multiplying both sides by 100
100x=100*4.1363636...
100x=413.63636 .....
We can write it in term of x
100x=x+409.5
On subtracting both sides by x
100-x=409.5
99x = 409 .5
On dividing both sides by 99
x=[tex]\frac{409.5}{99}[/tex]
x=[tex]\frac{4095}{990}[/tex]
x=[tex]\frac{819}{198}[/tex]
On dividing both number by 9
x=[tex]\frac{91}{22}[/tex]
Therefore, x =[tex]\frac{91}{22}[/tex]
what is the sum of (3x^2y+4xy^2-2y^3+3) and (x^2y+2y^3-4)
Answer:
This is the sum ---> 4x^2y + 4xy^2 - 1
Step-by-step explanation:
(3x^2y+4xy^2-2y^3+3) + (x^2y+2y^3-4)
(remove the parenthesis)
= 3x^2y + 4xy^2 - 2y^3 + 3 + x^2y + 2y^3 - 4
(now, group the like terms)
= -2y^3 + 2y^3 + 4xy^2 + 3x^2y + x^2y + 3 - 4
(add the elements you think are alike or similar)
= -2y^3 + 2y^3 + 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y - 1
Answer:
the sum is 4x^2y + 4xy^2 - 1
27. You are researching the price of a phone. You found an average price of $320.00. One phone cost $295 and another cost $375. Find the price of the third phone.
Answer:
$290
Step-by-step explanation:
Assuming there are only three phones, let x = the third phone's price
We already got the prices of the two phones: $295 and $375.
(295 + 375 + x)/3 = 320
First, multiply both sides by 3 to isolate the expression in the parenthesis.
[(295 + 375 + x)/3 = 320]3
295 + 375 + x = 960
670 + x = 960
Subtract 670 from both sides
670 + x = 960
- 670 - 670
x = 290

Simplify the following
Improper fraction 16/5
Answer:
[tex]{ \sf{ = 3 \frac{1}{5} }}[/tex]
Answer:
3 1/5
Step-by-step explanation:
5 goes into 16 , 3 times with a remainder of 1.
so this leaves you with 3 1/5
Alternatively you can divide 16/5 to get 3.2 this gives the fraction 3 2/10 witch can be simplified to 3 1/5

factorise out a and x :

Solve the following using substitution
Y = 2X + 4
Y = 0.5x - 2
Answer:
x=−4 and y=−4
Step-by-step explanation:
Let's solve your system by substitution.
y=2x+4;y=0.5x−2
Step: Solve y=2x+4for y:
y=2x+4
Step: Substitute 2x+4for y in y=0.5x−2:
y=0.5x−2
2x+4=0.5x−2
2x+4+−0.5x=0.5x−2+−0.5x(Add -0.5x to both sides)
1.5x+4=−2
1.5x+4+−4=−2+−4(Add -4 to both sides)
1.5x=−6
1.5x
1.5
=
−6
1.5
(Divide both sides by 1.5)
x=−4
Step: Substitute−4 fo rx in y=2x+4:
y=2x+4
y=(2)(−4)+4
y=−4(Simplify both sides of the equation)
Answer:
x=−4 and y=−4

#Let'sLearnWhat is the solution
y=-x+2
y=-3x-2
Answer: (-2, 4)
Concept:
There are three general ways to solve systems of equations:
Elimination: using addition/subtraction to cancel out variables.Substitution: when two variables appear in both equations and are isolated, they could substitute each other.Graphing: graph the equations to find the intersection for the solution.Here we are going to use substitution since the variable [y] is being isolated in both equations.
Solve:
Given equations
y = -x + 2
y = -3x - 2
Using the method of substitution to combine the equations
-x + 2 = -3x - 2
Add 3x on both sides
-x + 2 + 3x = -3x - 2 + 3x
2x + 2 = -2
Subtract 2 on both sides
2x + 2 - 2 = -2 - 2
2x = -4
Divide 2 on both sides
2x / 2 = -4 / 2
[tex]\boxed{x=-2}[/tex]
Find the y value
y = -x + 2 →→→ Given expression
y = -(-2) + 2 →→→ Substitute values into the expression
y = 2 + 2 →→→ Simplify the value
[tex]\boxed{y=4}[/tex] →→→ SImplify by addition
