Answer: Choice C
x+y = 28
3x+4y = 100
===================================================
Explanation:
x and y are placeholders for nonnegative whole numbers.
Specifically,
x = number of three point questions
y = number of four point questions
Since we have 28 questions total, this must mean x+y = 28. That forms the first equation in our system of equations.
------------
Now let's form the second equation:
x = number of three point questions
3x = points we get from all the three point questions
y = number of four point questions
4y = points we get from all the four point questions
3x+4y = all points possible
3x+4y = 100 is the second equation
------------
So we have this system
[tex]\begin{cases}x+y = 28\\3x+4y = 100\end{cases}[/tex]
which fits the conditions in the instructions.
Lines / and m parallel. Can be represented by the 3x+4y=8. If line m passes thorough the point (2,-5), which equation can be used to find the equation of line m
Answer:
y=−34x+2.75
Step-by-step explanation:
Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form.
3x + 4y = 12
4y = –3x + 12
y = –(3/4)x + 3
slope = –3/4
We know that the second line will also have a slope of –3/4, and we are given the point (1,2). We can set up an equation in slope-intercept form and use these values to solve for the y-intercept.
y = mx + b
2 = –3/4(1) + b
2 = –3/4 + b
b = 2 + 3/4 = 2.75
Plug the y-intercept back into the equation to get our final answer.
y = –(3/4)x + 2.75

Casey currently owes $500 to his parents. He plans to pay them $60 per month until it is
paid off. Sally also owes her parents money. She borrowed $600 from them and plans to
pay them back $80 per month. Is there a time when they will both owe their parents the
same amount of money?
Answer:
They will both owe their parents $200 when Casey is paying his 5th month and Sally is paying on her 5th month.
Step-by-step explanation:
If Casey pays 60 dollars after 5 months, he will have payed $300 dollars. He still needs to pay $200.(500-300) If Sally pays 80 dollars after 5 months, she will have payed $400 dollars. She still needs to pay $200. (600-400)

The slope of the line 5x + y = 15 is___
Answer:
x = -1/5y +3
Step-by-step explanation:
add -y to both sides
5x + y + -y = 15 + -y
5x = -y + 15
step 2 divide both sides by 5
5x/5 = -y +15/5
x= -1/5 y +3
Answer
x= -1/5 y + 3

A baseball team has won 20 games and lost 10 games. What percent of the games did the team win?
Answer:
They won 2/3 of the games, or about %66 percent.
Step-by-step explanation:
There is a total of 30 games played, becuase 20+10 is 30, and they won 20 out of 30 of the games. or 20/30. You then divide 20/30 and you will get .6666 which is 66%.
Answer:
30 %
Step-by-step explanation:
20×10=30
Or
20+10=40
What’s 123.45 + 67.891
Step By Step?
Answer:
123.45 + 67.891 = 191.341
Step-by-step explanation:
I don't know really know how to explain but I'll try to. So since 123.45 is the larger decimal so you put it first then below it you put 67.891.(not that it is necessary)
Then add a zero to 124.45. Meaning it will be 123.450. (It is the same number, we just have to add a zero there.)
Add then just add like you normally do. Just try doing it and you'll see.
I need help ASAP pic below
Answer:
Step-by-step explanation:
2) ∠A + ∠B = 146 {Exterior angle theorem}
5y + 3 + 4y + 8 = 146
5y + 4y + 3 + 8 = 146 {combine like terms}
9y + 11 = 146
9y = 146 -11
9y = 135
y = 135/9
y = 15
3) m∠A = 5y + 3
= 5*15 + 3
= 75 + 3
∠A = 78
4) m∠B = 4y + 8
= 4*15 + 8
= 60 + 8
m∠B = 68
5) m∠ACB + m∠A + m∠B = 180 {Angle sum property of triangle}
m∠ACB + 78 + 68 = 180
m∠ACB + 146 = 180
m∠ACB = 180 - 146
m∠ACB = 34

#surfacearea
Answer:
773 or 278.5 (if it only wants the sides the pic shows)
Step-by-step explanation:
13*5=65
65/2=32.5 (since it is a triangle you by 2)
12*9=108
108/2=54
15*20=300 (it is a square so you leave it)
you do it on the other sides that you can't see in the pic.
Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773
Hope this helps!
What is the equation of the line that passes through the point (3,-5) and has a
slope of o?
Answer:
y = -5
Step-by-step explanation:
slope of 0 means m = 0 in y intercept form y = mx + b.
they have given you (3, -5), plug these in and solve for your equation.
remember, a line that has a 0 slope means it is a horizontal line.
y = mx + b
-5 = 0(3) + b
-5 = b
so you have, y = -5.

Please help !! Which statement best describes the data ?
Answer:
The correct statement is C.
Step-by-step explanation:
A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
1. Minimum (shown towards the left of the chart)
2. First Quartile (shown by the left-most line of the box)
3. Median (or the second quartile) (shown as a line in the center of the box)
4. Third Quartile (shown by the right-most line of the box)
5. Maximum (shown towards the right of the chart).
From the provided box plot it can be concluded that:
Minimum = 3First Quartile = 6Median = 9Third Quartile = 12Maximum = 15The median is a quantity in statistics that points out where the mid-value of a data set is. Half of the data is less than the median and half is more than the median.
The median is 9, i.e. half of the data is less than 9 and half is more than 9.
The correct statement is C.

what is the answer to x - 8 < -2
Answer:
X < 6
Step-by-step explanation:
Add 8 to both sides
x < 6
Answer:
X<6
Step-by-step explanation:
x-8<-2
So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.
x-8<-2
+8 +8
X<-2+8
Next, You need to add alike terms.
X<6
