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
You're good to go!

Maria got 4 answers wrong as per linear equation.
What is a linear equation?
A linear equation is an equation that has a variable with the highest power of 1. A linear equation may consists of multiple variable. However, the highest power of any variable will be 1.
Given, Maria's math test had 25 questions.
She got 84% correct.
Therefore, she got wrong
= (100 - 84)%
= 16%
Now, the number of questions she got wrong is

B. If 200 people were surveyed, men and women, .10+.15/ .25 of those people like reading... so I multiplied 200x.25 to get 50. Meaning 50 people like reading.
C. If we know 130 men were surveyed then we’d subtract that amount from 200 which is the overall amount of people to get the amount of women surveyed which is 70.

Answer:
Percentage of error by Clare is estimated as 4.1667 %.
Step-by-step explanation:
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
Final answer:
The doctor's measurement is the actual height. The error in Clare's estimation is 2 inches or 4% of the total height.
Explanation:
The doctor's measurement should be considered the actual height because it is the factual measurement obtained, while Clare's was an estimate based on her observation.
The error in Clare's estimate, compared to the actual height, is 2 inches. To calculate the error as a percentage, we first convert the actual height to inches (50 inches = 4 feet 2 inches), then divide the error by the actual height and multiply by 100 to get the percentage.
So, the error as a percentage is (2/50)×100 = 4%.
