9 – nx = 17nx solve for x Explain how to do it
Answers
x = 1/2n
Subtract 17nx from both sides
9−nx−17nx = 0
Combine −nx and −17nx to get −18nx
9 −18nx = 0
Subtract 9 from both sides
−18nx = −9
The equation is in standard form
(−18n)x=−9
Divide both sides by −18n
(-18n)x/ -18n = -9/ -18n
Dividing by −18n undoes the multiplication by −18n
x= -9/ -18n
Divide −9 by −18n
x= 1/2n

What is the slope of a line that goes through the points (3,7) and (8, 11)
Answers
Answer:
The answer is
[tex] \huge \frac{4}{5} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{11 - 7}{8 - 3} = \frac{4}{5} \\ [/tex]
We have the final answer as

Teri and Lee are playing a game that consists of consists of spinning a spinner with eight equal spaces numbered 1 through 8, and then flipping two coins at the same time.
Terri wins 10 points if the spin is greater than 5 and the coins are different (one head and one tail).
Lee wins 15 points if the spin is an even number and the coins are both tails.
Is the game is fair or unfair? Why?
A.The game is not fair, because Terri’s expected value is 10(4/8)(2/4)=2.5 and Lee’s expected value is 15(4/8)(1/4)=1.875.
B.The game is fair, because Terri’s expected value is 10(3/8)(2/4)=1.875 and Lee’s expected value is 15(4/8)(1/4)=1.875.
C.The game is not fair, because Terri’s expected value is 10(38)(13)=1.25 and Lee’s expected value is 15(4/8)(1/3)=2.5.

Answer:
the slope of the line is -10 and it represents the rate of which the liquid is leaking out of the container
Step-by-step explanation:
find any 2 points on the line. i chose (10,800) and (20,700)
the formula for slope is m = y2-y1 divided by x2-x1
plug the numbers in, then solve and it should be
m = 800-700 / 10 - 20
m = 100 / -10
m = -10

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of girls in the class be = G
Now , let the total number of boys in the class be = B
The total number of students in the class = S
The value of S = 30 students
The percentage of boys in the class = 40 %
So , the equation will be
The number of boys in the class = percentage of boys in the class x total number of students in the class
Substituting the values in the equation , we get
The number of boys in the class = ( 40/100 ) x 30
The number of boys in the class = 30 x 0.4
The number of boys in the class = 12 boys
So , the number of girls in the class = total number of students in the class - number of boys in the class
Substituting the values in the equation , we get
The number of girls in the class = 30 - 12
The number of girls in the class = 18 girls
Therefore , the value of G is 18 girls
Hence , The number of girls in the class is 60% or 18 girls

-2x - 3(2x - 4) = 4(x – 6)
3(x - 2) = x + 2x - 5
Answers
Answer:
x = 3
No Solution
Step-by-step explanation:
-2x - 3(2x - 4) = 4(x – 6) this means x would equal 3 because if you isolate the variable by dividing each side by factors that don't contain the variable.
3(x - 2) = x + 2x - 5 would have no solution because there are no values of x that make the equation true.
