On an algebra test, a total of 50 students had grades of B or C. There were 10 more students with C’s than B’s. Find the number of students who had a B and the number of students who had a C.

Answers

Answer 1

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

Answer 2

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.

Answers

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

A line with a slope of 9 passes through the points (-7,-10) and (-6,g).What is the value of g?

Answers

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

10(p-7)=180 solve for p

Answers

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.

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

Answers

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.
