Let the students with B(s) be x.
So, the students with C should 10 more than x = x + 10
Total students = 50
=> students with B + students with C = 50
=> x + (x + 10) = 50
=> 2x + 10 = 50
=> 2x = 50 - 10 = 40
=> x = 40/2 = 20
Thus,
students with B = x = 20
students with C = x + 10 = 20+10= 30
Number of students who had a B are 20.
And, Number of students who had a C are 30.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
There are 50 students who had grades of B or C.
There were 10 more students with C’s than B’s.
Now,
Let number of students who had grade B = x
So, The number of students who had grade C = x + 10
So, we can formulate;
x + (x + 10) = 50
x + x + 10 = 50
2x + 10 = 50
2x = 50 - 10
2x = 40
x = 20
Thus, The number of students who had grade B = x
= 20
So, The number of students who had grade C = x + 10
= 20 + 10
= 30
Therefore, Number of students who had a B are 20.
And, Number of students who had a C are 30.

Point slope form of (-2,3) and (-1,-2)
Answer:
y= -5x-7
Step-by-step explanation:
Hope this helps!
Please anyone help me on this
Answer:
Standard line equation:
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
y=1.5x-6.5

Moore has 20 songs. His friend bought him M more songs. Write an expression that shows how many songs Moore has now.
Answer:
20 + M = number of songs Moore has now
Step-by-step explanation:
Moore started with 20 songs, so you would need to add the number of songs his friend bought him (M) to the 20 that he already has which will show the total number of songs Moore has.

Solve these multi step equations. Show your work. Justify each of your steps. 3(x-8)=10x+18
Answer:
The answer is x= -6
Step-by-step explanation:
3(x-8)=10x+18
3x-24=10x+18
3x-24=10x+18
Both side +24
3x=18+24+10x
Both side -10 x
3x-10x=42
-7x= 42
Both side divided by 7
x= -6

A line with a slope of 9 passes through the points (-7,-10) and (-6,g).What is the value of g?
Answer:
g = -1
Step-by-step explanation:
Given the following data;
Slope, m = 9
Points = (-7, -10) and (-6, g)
X-axis = x1, x2 = (-7, -6)
Y-axis = (y1, y2) = (-10, g)
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
9 = (g - (-10))/(-6 - (-7)
9 = (g + 10)/(-6 + 7)
9 = (g + 10)/1
Cross-multiplying, we have;
9 = g + 10
g = 9 - 10
g = -1

2. Many people think Michael Jordan is the greatest basketball player of all time, with a career scoring average of 30.1 points per game. Some curious statistics students wondered about his scoring average for all his home games. They decided to take a random sample of 15 home games from Michael Jordan's career. Here is the number of points he scored in each of these games: 35 24 29 31 25 28 35 32 36 31 29 26 32 38 27 Construct and interpret a 95% confidence interval for the mean number of points that Michael Jordan scored in all of his home games.
Answer:
I am 95% confident that the interval from 28.204 to 32.863 captures the true mean PPG of all of Jordan's home games.

10(p-7)=180 solve for p
Answer
The answer is p=25
Answer:
p = 25
Step-by-step explanation:
Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
~
First, divide 10 from both sides of the equation:
(10(p - 7))/10 = (180)/10
p - 7 = 180/10
p - 7 = 18
Next, add 7 to both sides of the equation:
p - 7 (+7) = 18 (+7)
p = 18 + 7
p = 25
25 is your answer for p.

PLEASE HELP!!!
Answer:
Step-by-step explanation:
Line segment divided into 5:3 ratio, so one segment is ⅝ of AB and one segment is ⅜ of AB.
Compare the coordinates of A and B.
change in x-coordinates = 10-2 = 8
change in y-coordinates = 2-(-6) = 8
⅝ of 8 = 5, so x-coordinate of C = (x-coordinate of A) + 5 = 7, and y-coordinate of C = (y-coordinate of A) + 5 = 1
Three friends have done some job together and got paid and now they need to share
the money. The first friend gets $500 and of the rest of the money. After he took
his part, the second friend gets $800 and of the rest of the money. The third friend
gets $900. Which friend got the greatest amount?
Answer:
Third friend with $900
Step-by-step explanation:
All-in-all each individual got a specific amount of cash that is mentioned in the question. If we compare each of their amounts we can easily say that the third friend got the greatest amount which is $900. This is $400 more than the first friend and $100 more than the second friend. This would be different if the values were percentages instead of actual dollar values.

8. Two coins are flipped. What is the probability that both of the coins land heads up?
Answer:
1/4
Step-by-step explanation:
1/2 x 1/2
Step-by-step explanation:
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
