Answer: Vaughn collected 72 pieces of litter.
Step-by-step explanation: The equation is correct. You get that by going backwards through the information in the story.
Vaughn's number is x.
Piper is 1/4 x
Sara is Piper +12 So (1/4 x)+12
Dom is Sara -15. So (1/4 x) -3
Add all Piper, Sara & Dom on one side of the equation.
The other side is the Vaughn's amount minus 9 because it says he picked up 9 more than the others combined. So x-9 equals the amount of the other three combined.
The three 1/4 x add to 3/4 x
Skipping to the solution:
x - 3/4 = 12 -3 +9
1/4 x = 18 Multiply both sides by 4
x = 72
1/4 x is 18, Piper's number.
Use that to calculate the Sara and Dominique.
The sum of the measures of angle P and angle Q is 90°.
The measure of angle P is (2x−10)°.
The measure of angle Q is 60°.
What is the value of x?
Answers
Answer:
The measure of the second angle is,. 2a=2×60° =120°.
Step-by-step explanation:Supplementary angles are two angles whose measures add up to 180° .
The two angles of a linear pair, like ∠1 and ∠2 in the figure below, are always supplementary.
But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180°.
Answer:
x=20
Step-by-step explanation:
since the value of angle P and Q adds up to 90°,
(2x-10)+60=90.
shift -10 and 60 to the right hand side of the equation,
2x=90-60+10
2x=40
divide both sides by 2,
x=40÷2
x=20
hence, the value of x is 20

Amanda enjoys cycling. The graph shows the relationship between the number of hours she rides her bike, x, and the number of miles she covers.
The equation that represents the relationship between the number of hours she rides, x, and the distance she covers, y, is
.
Using the equation, the distance she would cover if she rode for 1.5 hours would be
miles.
Answers
Answer:
21
Step-by-step explanation:
Of you check the graph the distance between 14 and 28 is 7, so every number of the number of miles has a distance of 14 miles. 14+7=21. The line crosses 1.5 hours when it crosses 21 miles.

Answers
Answer:
The answer is Mark will have 1 1/4 paint left.
Step-by-step explanation:
First, I made all the fractions into mixed numbers
Secondly, I made all the fractions have a common denominator of 120, because it's the lcm of the numbers 5,6, and 8.
Then I subtracted 3/4 or 80/120 from all of the fractions.
I got 150/120 which is 1 1/4

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!
So player 5 scored 5 points

What is the probability of rolling a number less than or equal to 5 on a fair number
cube? Justify your answer.
Answers
Answer:
Step-by-step explanation:
The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.
Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.
