Brandi spent 25 mins, which is 5/8 of her class period taking notes. How long was the class period?
Answer:
The class period was 45 minutes long
Step-by-step explanation:
as you can see 5/8 of the class is 25 minutes, meaning that 1 = 5 if we multiply 8 times 5, it gives 45.
Answer: I believe your answer is 40 minutes for Brandi's class period.
Step-by-step explanation: For every 5 minutes she spends in class, it is 1/8 of her total period of class time. For example, she spent 25 minutes and has 15 minutes or 3/8 left of class.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x+3-(8*(5*x+5))=0
Pull out like factors :
5x + 5 = 5 • (x + 1) 3x + 3) - 40 • (x + 1) = 0
-37 = 0 but nozero's can't be converted so
Solve : x+1 = 0
Subtract 1 from both sides of the equation :

= In circle V, VW = 8 and m<WVX = 20°. Find the length of arch W X. Express your answer as a fraction times pi.
The length of the arc WX is the number of units on the arc
The length of the arc WX is [tex]\frac{8}{9} \pi[/tex]
How to determine the length of the arc WX?The given parameters are:
Central angle, m<WVX = 20 degrees
Radius, VW = 8
The length (L) of the arc is calculated as:
[tex]L = \frac{\theta}{360} * 2\pi r[/tex]
Substitute known values
[tex]L = \frac{20}{360} * 2\pi *8[/tex]
Evaluate the product
[tex]L = \frac{320}{360} \pi[/tex]
Simplify the fraction
[tex]L =\frac{8}{9} \pi[/tex]
Hence, the length of the arc is [tex]\frac{8}{9} \pi[/tex]

Answer:
It is C
Step-by-step explanation:
So 3.75 is the rate of change, when she goes to get a drink it changes it subtracts the amount which Mia has which is $50. so we could put y=-3.75x+50 as the equation because for the number of drink she buys multiply by how much she cost will be the money she has to spend, so by subtracting by 50 her gift card will give how much money she will have in her gift card
Hope this helps
Answer: y= -3.75x + 50
Each drink costs Mia $3.75. Since spending money causes her to lose money, this value will be negative. Therefore, we will put -3.75x in the beginning of the equation.
Mia has $50 on a gift card. Since this amount is positive (she has a positive amount of money) and remains constant (the amount on the gift card won't change) we will put +50 at the end of the equation.

HELP ASAP I GIVE 60 points total and big brain!!!! Solve the system of equations by substitution. If there is one solution, express it as an ordered pair. If there is no solution, write no solution. If there is an infinite number of solutions, write infinite number of solutions.
x−y=−5x
x−y=1/3
Solution:
Given:
x - y = -5xx - y = 1/3Substitute the value of "x - y" into equation 1.
x - y = -5x1/3 = -5xDivide -5 both sides.
1/3 ÷ -5 = -5x/-51/3 x 1/-5 = xx = 1/-15 = -1/15Substitute the value of x into equation 2.
x - y = 1/3-1/15 - y = 1/3-1/15 - y = 5/15-y = 5/15 + 1/15y = -6/15 = -2/5Putting the solutions in (x,y) form.
⇒ (x,y) ⇒ (-1/15, -2/5)Answer:
(x, y) = (-1/15, -2/5)
Step-by-step explanation:
You want to solve the system of equations by substitution:
x -y = -5xx -y = 1/3SubstitutionWe can use the second equation to substitute for (x-y) in the first equation:
1/3 = -5x
-1/15 = x . . . . . . . . divide by -5
Substituting this value into the second equation, we have ...
-1/15 -y = 1/3
-1/15 -1/3 = y = -6/15 = -2/5
The solution is (x, y) = (-1/15, -2/5).

Matthew's dad hired him to paint 6 wooden patio chairs for $125. It takes him 9 hours to paint all of the chairs. If it takes the same amount of time to paint each chair, what fraction of an hour does it take Matthew to paint one chair? Justify your thinking with a model.
Given:
Matthew's dad hired him to paint 6 wooden patio chairs for $125.
Time taken by him to paint all of the chairs = 9 hours.
It takes the same amount of time to paint each chair.
To find:
The fraction of an hour does it take Matthew to paint one chair
Solution:
Total time = 9 hours
Total number of chairs = 6
Now, time taken by Matthew to paint one chair is
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{9}{6}[/tex]
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{3}{2}[/tex]
Therefore, Mattew takes [tex]\dfrac{3}{2}[/tex] of an hour to paint one chair.
Thinking with a model: On dividing the total time by total number of chairs we get time taken by Mattew (in hours) to paint one chair. So, the result represents the fraction of an hour taken by Matthew to paint one chair.
