Which verbal expression is represented by 1/2 (n-3)
(A) One-half n decreased by 3
(B)One-half n subtracted from 3
(C)The difference of one-half n and 3
(D)One-half the difference of n and 3
Answer: (D)One-half the difference of n and 3
Step-by-step explanation:
The correct verbal expression for the function f(n) = 1/2 (n-3) is →
One-half the difference of n and 3.
What is a verbal expression in mathematics?
A mathematical expression when written using verbal statements is known as the verbal expression of that mathematical expression.
Given is the following mathematical expression -
f(n) = 1/2 (n-3)
The given expression is -
f(n) = 1/2 (n-3)
Now, Assume A = (n - 3) represents the the difference of n and 3.
1/2 (A) represents its one half.
Therefore, the correct verbal expression for the function f(n) = 1/2 (n-3) is → One-half the difference of n and 3.

how long will a section of a railroad track be if it rises 6.8m for a run of 125.6 m
Answer:
The length of the section will have 125.8 m
Step-by-step explanation:
Right Triangle
The section of the railroad track rises a height of h=6.8 m for a horizontal run of x=125.6 m.
The height and the horizontal run are the legs of a right triangle which hypotenuse L is the required length of the section of the railroad track.
Applying Pythagora's Theorem:
[tex]L^2=h^2+x^2[/tex]
[tex]L^2=6.8^2+125.6^2[/tex]
[tex]L^2=46.24+15775.36=15821.6[/tex]
[tex]L=\sqrt{15821.6}=125.8[/tex]
The length of the section will have 125.8 m
The ratio of Kailyn's money to Nathan's money is 4:9. If Nathan has $45, how much do
they have all together? (I need help asap)
Answer:
$65Step-by-step explanation:
Step one:
we are told that the ratio of Kailyn's money to Nathan's money is
4:9,
Nathan has $45, let Kailyn's money be x
therefore
4/9=x/45
cross multiply we have
9x=45*4
9x=180
divide both sides by 9
x=180/9
x=20
Kailyn's money is $20
Together they have =20+45= $65

Use the elimination method to solve the system of equations. Choose the correct ordered pair.
-x + y = -2
2x - 3y = 4
A. (3, 1)
B. (4, 2)
C. (2, 0)
D. (5, 3)
Answer:
C. (2, 0)
Step-by-step explanation:
-x + y = -2
2x - 3y = 4
Multiply both sides of the first equation by 2.
Write the second equation below it and add them.
-2x + 2y = -4
(+) 2x - 3y = 4
----------------------------
-y = 0
y = 0
Start again with the original equations.
Multiply both sides of the first equation by 3. Write the second original equation below it and add them.
-3x + 3y = -6
(+) 2x - 3y = 4
-------------------------
-x = -2
x = 2

how to find the factors of 82
Answer:
Step-by-step explanation:
What is 82 dividend by 3 and keep dividing intill you cant any more and you got your answer
Answer:
To find factors, you can either divide 82 by each number from 1 to 10 (which seems to work most of the time, but if it doesn't continue onward with the numbers), or you could see what, when multiplied, equals 82. But remember these must not be decimals or fractions.
The factors are 1, 2, 41, 82

Answer:
A
Step-by-step explanation:
The answer is A because the slope is 1/2, and according to rise over run, the line goes up 1 and to the right 2, which is correct. The y-intercept is also 1, as the line goes through 1 on the y axis.
