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

y = -|x + 2| - 4
y = -|x - 2] + 4
y = -|x - 2| - 4
Answers
Answer:
y = -|x - 2| + 4
Step-by-step explanation:
The parent function of the absolute value function is y = |x|. There is a negative reflection in the x-axis, a horizontal translation of 2 units right, and a vertical translation of 4 units up.

Work Shown below& answers I need an (a) equation for Tyler’s age x ,,,(b) how old is Tyler for (c) how old is Samantha. I need help please
Answers
Answer:
Step-by-step explanation:
tyler is x years old
t = x
samantha is 4 years older then tyler...
x + 4....this is samanthas age
three times samanthas age = 60
3(x + 4) = 60
3(x + 4) = 60 <=== this is an equation for tylers age....x = tylers age
3x + 12 = 60
3x = 60 - 12
3x = 48
x = 48/3
x = 16 <==== tyler is 16 years old
samantha is : x + 4.....16 + 4 = 20 <=== samantha is 20

32/128 = x/100
32 * 100 = 3200
128 * x = 128x.
Now we have 128x = 3200.
All we need to do is divide 3200 by 128, so 3200 / 128 = 25, so your answer is 25%.
