A washing machine is on clearance for 30% off. If the sale price of the washing machine is $395.49, what was the original price? Round to the nearest cent if necessary. Justify your solution.
Answers
Answer:
Discount = Original Price x Discount %/100
Discount = 395.49 × 30/100
Discount = 395.49 x 0.3
You save = £118.65
Final Price = Original Price - Discount
Final Price = 395.49 - 118.647
Final Price = £276.84. (ANSWER)
original price of washing machine is $564.99 if the sale price of the washing machine is $395.49 with 30% off.
What is Percentage?Percentage is defined as a given part or amount in every hundred
Based on the given conditions, formulate:
x×(1-30%)=395.49
Apply multiplicative distribution
x-0.3x=395.49
Combine the like terms
0.7x=395.49
x=395.49/0.7
Convert decimal to fractions
x=(39549/100)/(7/10)
x=39549/(10×7)
x=39549/70
x=564.99
Hence original price of washing machine is $564.99

Answer:
You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m
Step-by-step explanation:
Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

Step-by-step explanation:
Using the distributive property:
[tex]-23x(x+3)[/tex]
You will multiply both the x and the 3 inside the parantheses by the -23x outside.
[tex]-23x[/tex] · [tex]x = -23x^{2}[/tex]
Then:
[tex]-23x[/tex] · [tex]3 = -69x[/tex]

27x - 4 = 18x + 2 + 30
27x - 4 = 18x + 32
Add 4 to both sides
27x = 18x + 32 + 4
27x = 18x + 36
Subtract 18x from both sides
27x - 18x = 36
9x = 36
Divide both sides by 9
x = 36/9
x = 4
∠JTS = 27x - 4
= 27*4 - 4

I need help with this Trig Problem Asap
Answers
Answer:
Step-by-step explanation:
A function is one-to-one if it passes the horizontal line test. This is the case if a horizontal line intersects the graph in only one place.
The graph of f(x) = x^2 - 5 is that of a parabola that opens upward. There are several possibilities here:
1. The horizontal line intersects the parabolic graph twice on the interval (-infinity,+infinity). Therefore this function is not one-to-one on this interval
(-infinity,+infinity).
2. If we define the domain as [0,+infinity), a horizontal line will intersect this parabolic graph only once. Therefore this function is one-to-one on [0,+infinity).

The question is in the picture
Answers
Therefore, we need to find the slope (“m”) of the line (change in y/change in x), which is rise/run. We also need to find the y-intercept (“b.”)
1.) (0, -3) (1, -1)
We took two points from the line to find the slope. We will use the 2 coordinate pairs to find the slope.
2.) m=(y2-y1)/(x2-x1)
This is the slope “m” formula.
3.) m=( -1+3)/(1-0)
Input the coordinate values into the formula. The +3 you see is due to -(-3)=+3.
4.) m=2/1
We simplified the above formula.
5.) m=2
By division.
We now have the slope or “m.” M=2. Therefore, the equation rises 2 units and runs 1 unit.
Now, finding the y-intercept:
The y-intercept or “b” is where the line intersects the y-axis. It is the starting point of a linear equation.
To find the y-intercept, we need to figure out what the output is when the input is 0. We can see on the table in the picture that with an input of 0, the output is -3.
Therefore, b=-3. This is because an input of 0 means that there is no movement on the x-axis, so we can determine where the where the linear intercepts the y-axis.
Therefore, the equation is y=2x-3, where m=2 and b=-3.
That’s the answer: y=2x-3

B) (3/2 , 6)
C) (2 , 7)
D) infinite solutions
Answers
To graph a linear equation, first you plot the y-intercept, then move the point depending on your slope.
First, you need to solve 4x - 2y = -6. So you subtract 4x on both sides, then divide each side by -2. This gives you y = 2x + 3.
Y = 2x + 3 is point (1, 5) on the graph. And since the graphs of the equations are the same, there are infinite solutions.

one number is 15 more than a second number.The sum of the number 115. What are the numbers?
Answers
The second number is 50
X= first number
Y= second number
X+Y= 115 > or 2y+15= 115 > subtract 15 from both side
2y= 100> divide by 2 on each side> y=50
There you have solved for y, now solve x
X= 50+15 > which is 65
So therefore, the first number is 65 and the second is 50.

If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?
solution :
the area of each face of the cube = side × side
= X × X = X²
the cube has 6 similar faces, so the surface area of the cube could be:
S = 6 × X² = 6X²
Answer:
Surface Area = 6 × S²
Step-by-step explanation:
the surface area fo the cube :
SA = 6 × lenght × lenghtif lenght = S, the surface area fo the cube :
SA = 6 × lenght × lenght
SA = 6 × S × S
SA = 6 × S²

Tony bought a $48 sweatshirt and used a coupon for a 10% discount. Keith bought an identical sweatshirt at a different store for $42.95. Which statement is true?
Answers
Answer:
Keith paid $0.25 less than Tony paid.
Step-by-step explanation:
Tony paid ($48 - 10%) = $43.2
Keith paid $42.95.
The difference is Tony paid $0.25 more, or Keith paid $0.25 less.
Answer:
Keith paid $0.25 less than Tony.
Step-by-step explanation:
Tony: 48 x 0.10 = 4.8
48 - 4.8 = $ 43.20 (Tony)
Keith: $ 42.95
43.20 - 42.95 = 0.25
