A bike is on sale for $135. It has been marked down 20%. What was the original price of the bike?
Answers
Answer:
$168.75
Step-by-step explanation:
if it's narked down by 20% then $135 is 80% of the original price
80 = 135
100 = x
80x = 100×135
x = $168.75
A bike is on sale for $135. The original price of bike is 135
Solution:
Given that bike is on sale for $ 135
The mark down price is 20 %
We need to find the original price of the bike
Hence we can say that,
Selling price of bike = 135
Mark down price = 20%
Original price of bike = ?
The cost price is given as:
By substituting the values we get,
Hence the original price of bike is $ 168.75

The expression for the total cost of hiring a plumber will be equal to $50 + $40(h).
What is an expression?
Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given statement in the question,
The charge for a plumber to visit the house = $50
The additional charge per hour = $40
The expression for t hours will be,
A = $50 + $40(h),
Here, A is the total amount and h is the number of hours the plumber is working.

Final answer:
To solve this problem, set up an equation using the given weights and solve for 'x' to find the weights of each friend's bag.
Explanation:
To solve this problem, we need to set up an equation based on the given information.
First, let's express the weights of Randall's, Seth's, and Joanna's bags in terms of 'x':
- Randall's bag: 3x - 7 pounds
- Seth's bag: 2x - 10 pounds
- Joanna's bag: 2x + 2 pounds
According to the problem, Randall's and Joanna's bags together weigh 3 times as much as Seth's bag. Mathematically, this can be written as:
(3x - 7) + (2x + 2) = 3(2x - 10)
Solving this equation will give us the value of 'x', which we can then use to find the weights of each friend's bag.

Answer:
Randall=68 pounds, Seth's=40, Joanna's=52
Step-by-step explanation:
Randall's = 3x-7
Seth's = 2x-10
Joanna's = 2x+2
Randall's + Joanna's = 3 (Seth's)
Find X:
- Form into an equation (add parentheses)
- (3x-7) + (2x+2) = 3 (2x-10)
- REmove parentheses on left side
- 3x-7+2x+2 = 3 (2x-10)
- Distribute right side
- = 6x-30
- 3x-7+2x+2 = 6x-30
- Combine like terms
- 5x-5=6x-30
- subtract 5x from BOTH sides (always subtract, add, multiply, and divide both sides at the same time)
- -5=x-30
- Add 30 to BOTH sides
- 25=x
Find how many pounds of trash each friend picked up:
Randall's:
- 3x-7
- plug in x
- 3(25)-7
- Distribute
- 75-7
- = 68
Seth's:
- 2x-10
- 2(25)-10
- 50-10
- = 40
Joanna's:
- 2x+2
- 2(25)+2
- 50+2
- =52
Double check your answers:
Randall's+Joanna's= Seth's(3)
68+52=40(3)
120=120

prime factors of 126: 2x3x3x7
prime factors of 210: 7x3x5x2
now we multiply all the factors that they all have in common: 2x3x7 which is 42. So the highest common factor is 42

So if the vertex moved from x=11 to x=6, then the x coordinate decreased, so it moved to the left by 5 (11 - 6 = 5).
Also if the vertex moved from y=9 to y=4, then the y coordinate also decreased, so it moved downward by 5 (9 - 4 = 5).
