Answer:
The number of multiple-choice questions are 15.
Step-by-step explanation:
Mrs. Snell's math test has twenty questions and is worth 100 points.
The test consists of multiple-choice questions and short answer questions.
Let M represents the Multiple choice questions.
Let S represents the short answer question.
It is given that the total number of question are 20.
[tex]S+M=20[/tex] ...(1)
Also, multiple-choice questions worth 3 points each, and short answer questions worth 11 points each. The total worth of the test is 100 points.
[tex]11S+3M=100[/tex] ...(2)
Multiply equation (1) by 3 and subtract from equation (2).
[tex]11S+3M=100\\3S+3M=60\\\underline{-\:\:\: -\:\:\:\:\:\:\:\:-\:\:\:\:\:\:}\\8S\:\:\:\:\:\:\:\:\:\:\:\:\:=40\\S\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=5[/tex]
The total number of short answers is 5.
Put S=5 in equation 1.
[tex]5+M=20\\M=15[/tex]
Hence, the number of multiple-choice questions are 15.

What does the function f (14) = 11 mean
Answer:
In general, when y = f(x), you are substituting a permissible x value into function f & its calculated 'output' is the value for y. Then (x,y) is an ordered pair, i.e. coordinates of a point on the graph. ... So our ordered pair is (-14,11).
Answer: 11= y and 14=x
Step-by-step explanation: The x coordinate is 14 and the y coordinate is 11.

7y – 4 = 9y + 13 – 4y
A. y = 17/2
B. y =9/2
C. y=17/12
D. y= 3/4
Answer:
A
Step-by-step explanation:
Given
7y - 4 = 9y + 13 - 4y ( simplify right side )
7y - 4 = 5y + 13 ( subtract 5y from both sides )
2y - 4 = 13 ( add 4 to both sides )
2y = 17 ( divide both sides by 2 )
y = [tex]\frac{17}{2}[/tex]

Solve x-7y=16 for y
Answer:
y = (x-16)/7
Step-by-step explanation:
x - 7y = 16
~Subtract x to both sides
-7y = 16 - x
~Divide -7 to everything
y = (16-x)/7
Best of Luck!
Answer:
y = 1/7 x -16/7
Step-by-step explanation:
x-7y=16
Subtract x from each side
x-x-7y=16-x
-7y = -x+16
Divide each side by -7
-7y/-7 = -x/-7 +16/-7
y = 1/7 x -16/7

C=85x+60
Solve the equation for x
Answer:
( C - 60)/ 85 = x
Step-by-step explanation:
C=85x+60
subtract 60 from each side
C-60=85x+60-60
C - 60 = 85x
Divide each side by 85
( C - 60)/ 85 = 85x/85
( C - 60)/ 85 = x

Your soccer team isnt holding a silent auction dinner as a fundraiser to pay for school uniforms. The list shows all the expenses for the silent auction, 1) a tablet costs $280 2) football tickets that cost $100 3) a gift card that cost $20 4) the cost of the food is $400. The members of the soccer team will be selling tickets to the silent auction. A ticket to the silent auction includes chances to win prizes and dinner. The ticket cost is set so that 50 tickets will pay for the cost of food and prizes and food. Part a determine the cost per ticket. Part B build a function that can be used to find the total profit, f(x), the soccer team earns by selling x tickets. Show your work to build a function. Part C your soccer team needs to raise at least $300 more than the total cost of the expenses. What is the minimum number of tickets that must to be sold in order for your team to reach their goal? Use the mathematics to justify your response.
Answer:
A) $16
B) p(x) = 16x -800
C) 69 tickets
Step-by-step explanation:
A) The total of expenses is ...
$280 +100 +20 +400 = $800
If this is covered by 50 tickets, then a ticket must provide revenue of ...
$800/50 = $16
The cost per ticket is $16.
__
B) The profit is the difference between revenue and expenses. The revenue from sale of x tickets will be 16x. The expenses are fixed at 800, so the profit is ...
p(x) = 16x -800
__
C) We can find the number of tickets to sell (x) in order for profit to be at least $300 by solving the inequality ...
p(x) ≥ 300
16x -800 ≥ 300 . . . . . use the expression for p(x)
16x ≥ 1100 . . . . . . . . . add 800
x ≥ 68.75 . . . . . . . . . . divide by 16 . . . (the least satisfactory integer is 69)
In order to raise at least $300, the number of tickets sold must be at least 69.

2) M<3=37 find m<1
drawing not to scale
A)37
B)143
C)127
D)153
Answer:
A. C) x = 19
B. A) 37
Step-by-step explanation:
A. 7x - 8 = 6x + 11
7x - 8 - 6x = 6x + 11 - 6x
x - 8 = 11
x - 8 + 8 = 11 + 8
x = 19
B.
If m<3 = 37
<1 = <3
Therefore, m<1 must equal 37

Solve the equation y = ax − b for the variable x.
A. x = ya + b
B. x = a+by
C. x = y + ba
D. x = y+ba
Answer:
(y+b)/a = x
Step-by-step explanation:
y = ax − b
Add b to each side
y+b = ax − b+b
y+b =ax
Divide each side by a
(y+b)/a = ax/a
(y+b)/a = x
Answer:
its d
Step-by-step explanation:
because is you think about it x is y+ba
