What is N equal to? I think I know I want to make sure tho :/
Answer:
n = 5/7 or 0.7
Step-by-step explanation:
The goal is to isolate the variable N. First, you distribute the fractions to their repsective parentheses.
1/2(5n + 8) = 3/4(12 - 6n)
2.5n + 4 = 9 - 4.5n
2.5n + 4.5n = 9 - 4
7n = 5
Divide both sides by 7, and you get n = 5/7 or 0.7
For each graph write the domain and range using inequalities.
Answer:
to find the domain and range you need to take (x,y)
domain would be all the x coordinates in number order or 1,2,3,4. same for range but with the y-coordinates.
if you have r{2,2,2} then you should but just r;{2}
hope i helped

Malcolm wrote 294 more lines of code than Sheila. Sheila wrote 1,275 lines of code. How many lines of code did Malcolm write?
Answer: 1,569
Step-by-step explanation: you just add how much Sheila wrote and how much more the statement said Malcolm wrote.
Answer:
1,569
Step-by-step explanation:
Since it says Malcolm wrote 294 more lines than Sheila, Malcolm is going to have a higher number of lines of code than Sheila.
To solve:
1,275 + 294 = 1,569

In a normal distribution, 51 is the score that is two standard deviations above the mean, and 36 is the score one standard deviation below the mean. Find the mean
Answer:
The mean is 41
Step-by-step explanation:
Here , we are interested in finding the mean.
Firstly, let the standard deviation be x and the mean be y.
We are told that 51 is 2 standard deviations above the mean. What this mean is that if we subtract 2 standard deviations from 51, we will arrive at the mean.
Mathematically;
51 - 2(x) = y
y + 2x = 51 •••••••••(i)
We are also told that 36 is one standard deviation below the mean. What this mean is that if we subtract one standard deviation from the mean, we will have 36
Mathematically, that would be;
y-36 = x •••••••(ii)
Substitute ii into i directly;
We have
y + 2(y-36) = 51
y + 2y -72 = 51
3y -72 = 51
3y = 51 + 72
3y = 123
y = 123/3
y = 41

Answer:
-6/7
Step-by-step explanation:
since both fractions have a common denominator (bottom part of fraction) you would end up subtracting 4-10 which would give you a -6. the denominator stays 7 so you end up with -6/7
Find the value of each variable by getting a quadratic equation equal to 0 first, then solve. Justify x^2 + 32 = 12x
Answer:
x = 4 ; x = 8
Step-by-step explanation:
[tex]x^2 + 32 = 12x[/tex]
bring all the terms to one side and set equal to 0
[tex]x^2 - 12x + 32 = 0[/tex]
factor the polynomial
[tex](x-8)(x-4) = 0[/tex]
set each factor equal to zero and solve
[tex](x-8) = 0 \\x - 8 = 0 \\x = 8[/tex]
[tex](x-4)=0\\x-4 = 0\\x = 4[/tex]
The perimeter of a square is defined by the function p(s)=4s if the perimeter is no more than 48 cm, which statement describes the domain for s, the side length of the square?
A. 0 < s ≤ 12
B. [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 ]
C. All real numbers
D. s ≤ 12
Answer:
A. 0 < s ≤ 12Step-by-step explanation:
Given
p(s) = 4sIf
P ≤ 48Then
4s ≤ 48s ≤ 12Since perimeter can't be negative or zero, the domain will be:
0 < s ≤ 12Correct choice is A
The area of a square is given by A = 82, where s is the length of each side of the square.
If the area of a square room is 81 square meters, what is the length of 1 side of the room,
in meters?
Answer:
The area of the square being 81 sq m, each side will be 81^0.5 = 9 m. The perimeter is thus 4 times the side = 4*9 = 36 m. The sides of the square are the square root of the area (81m^2), which is 9m.

What is the supplement of a 110 degree angle
Answer: 70 degrees
Step-by-step explanation: The supplement of an angle is the angle that has to be added to make 180°. So, the supplement of 110° is 70° because 110+70= 180.
If one kilogram equals 2.2 pounds how many kilograms equal 112 pounds
Answer & Step-by-step explanation:
Assuming that there is a constant rate of change, we can use the equation:
[tex]y=kx[/tex]
k is the constant rate of change. Set up an equation in which the pounds are determined by the rate of change between kilograms and pounds:
[tex]1=k(2.2)[/tex]
Isolate the variable k:
[tex]\frac{1}{2.2}=\frac{k(2.2)}{2.2}\\\\\frac{1}{2.2}=k[/tex]
Set up another equation like so:
[tex]\frac{y}{x}=\frac{y}{x}[/tex]
Insert values:
[tex]\frac{1}{2.2}=\frac{y}{112}[/tex]
Solve for y. Cross multiply:
[tex]1(112)=2.2y\\\\112=2.2y[/tex]
Isolate the variable. Divide both sides by 2.2:
[tex]\frac{112}{2.2}=\frac{2.2y}{2.2} \\\\ y=50.9090...[/tex]
So, there are about 50.9 kilograms in 112 pounds.

Given ABCE is a rectangle, find the length of AD
Help me
Answer:
AD = 10
Step-by-step explanation:
It's given that ABCE is a rectangle.
Therefore, measure of opposite sides of the rectangle will be equal.
AB = EC
AB = ED + DC
12 = ED + 4
ED = 8
Measure of side AE = 6
Since, measure of interior angles of a rectangle = 90°
Therefore, ΔEAD will be a right triangle.
By Pythagoras theorem,
AD² = AE² + ED²
= 6² + 8²
AD = [tex]\sqrt{36+64}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
Therefore, measure of side AD = 10 units

1/2017 is smaller than 1/2016. 1/2018 is smaller than 1/2017. And 1/2018 is smaller than 1/2016. So we can rewrite this as:
[tex]2018 \times ((\frac{1}{2016} - \frac{1}{2017} ) + (\frac{1}{2017} - \frac{1}{2018}) - (\frac{1}{2016} - \frac{1}{2018}))[/tex]
Distribute:
[tex]2018 \times (\frac{1}{2016} - \frac{1}{2017} + \frac{1}{2017} - \frac{1}{2018} - \frac{1}{2016} + \frac{1}{2018})[/tex]
Simplify:
