Answers
Answer:
y = -x + 6
Step-by-step explanation:
you will carry the character "X" to the right hand side making it "-x"
Equation x + 2y = 6 is equivalent to y = 3 - x/2
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
x + 2y = 6,
Subtract x from both the sides,
x + 2y - x = 6 - x
2y = 6 - x
Divide both the sides by 2,
y = 3 - x/2
The equation x + 2y = 6 can be expressed as y = 3 - x/2.

Answers
Answer:
1. n is 1 or -1
2. x is 6 or -6
Step-by-step explanation:
1. |n| -4 = -3
|n| = -3 + 4

Answer:
[tex]\frac{5}{7\\}[/tex] * [tex]\frac{3}{3}[/tex] = [tex]\frac{15}{21}[/tex]
Step-by-step explanation:
To get an equivalent fraction, we multiply by a fraction that is equal to one. The purpose is to alter the denominator of the fraction. To get from a denominator of 7 to 21 we multiply by 3. Therefore we will multiply 5/7 by 3/3 to get the new equivalent fraction with a denominator of 21.

i.e. p/q
Where p and q are integers and q≠0.
Here:
The numerator is pThe denominator is qGiven the number
8
As number '8' can be written in the form p/q, so it is a rational number.

Answers
Answer:
The answer is 12.5
Steps:
8:64*100 =
( 8*100):64 =
800:64 = 12.5
All the steps:
Now we have: 8 is what percent of 64 = 12.5
Question: 8 is what percent of 64?
Percentage solution with steps:
Step 1: We make the assumption that 64 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that %100=64
Step 4: In the same vein, x%=8.
Step 5: This gives us a pair of simple equations:
%100=64(1)
x%=8(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 64/8
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 8/64
x =12.5%
Therefore, 8 is 12.5% of 64.

find the equations that describe the circle of radius 3 centered at (9, 2, 1) that is parallel to the xy-plane.
Answers
The equation that describe the circle of radius 3 centered at (9, 2, 1) that is parallel to the x y-plane is (x - 9)² + (y - 2)² = 9.
We know that the given coordinates correspond to a sphere.
The x, y coordinates for our search for a circle parallel to the x-y plane are (x, y) = (9, 2)
The circle's standard equation is (x - h)²+ (y - k)² = r², where h and k are the circle's x and y coordinates, respectively, and r is its radius.
So, we have:
h = 9 ;
k = 2 ;
r = 3;
the solution is (x - 9)² + (y - 2)² = 9.

The mean of 30 numbers is 18. What will be the new mean, if each observation is
increased by 2.
Answers
Answer:
The new mean will be 20.
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
The mean of n=30 numbers is [tex]\bar x=18[/tex]. If each observation is increased by 2, then xi'=xi+2 and the new mean value will be:
[tex]\displaystyle \bar x'=\frac{\sum x'_i}{30}[/tex]
[tex]\displaystyle \bar x'=\frac{\sum x_i+2}{30}[/tex]
[tex]\displaystyle \bar x'=\frac{\sum x_i}{30}+\frac{\sum 2}{30}[/tex]
The sum of 30 times 2 is 60, thus:
[tex]\displaystyle \bar x'=18+\frac{60}{30}=18+2=20[/tex]
The new mean will be 20.
Part 1: Students performed in a play on a Friday and a Saturday. For both performances, adult tickets cost a dollars each and student
tickets cost s dollars each.
On Friday, they sold 125 adult tickets and 65 student tickets, and collected $1,200. On Saturday, they sold 140 adult tickets and 50
student tickets, and collect $1,230.
This situation is represented by this system of equations:
125a +65 s = 1,200
140a +505 = 1,230
What could the equation 265a+115s=2,430 mean in this situation?
Part 2: The solution to the original system is the pair a=7 and s=5. Explain why it makes sense that this pair of values is also the solution to the equation 265a+115s=2430.
Answers
Answer:
Sum of the two separate equations.
The values satisfies the equation
Step-by-step explanation:
Given the equations for the two separate days :
125a +65 s = 1,200 - - - Friday
140a +50s = 1,230 - - - Saturday
265a+115s=2430 means the addition of the two separate equations which means the overall sales for the two days in one single equation.
B)
Because, Inputting the solution, satisfied the equation:
a = 7 ; s = 5
265a+115s=2430
265(7) + 115(5) = 2430
1855 + 575 = 2430
