Answer:
7/21+9/21=16/21
Hope it helps
Have a good day
Answer:
16/21
Step-by-step explanation:
[tex]\frac{3}{7}+\frac{1}{3}[/tex]
First, make them have a common denominator.
The least common factor of 7 and 3 is 21, so you can do
3/7 * 3/3 = 9/21
1/3 * 7/7 = 7/21
The new expression would be:
[tex]\frac{9}{21}+\frac{7}{21}[/tex]
[tex]\frac{16}{21}[/tex]
So the answer is 16/21

Answer:
250.35
Step-by-step explanation: pythagorean theorem
215^(2)+x^(2)=330^(2)
46225+x^(2)=108900
x^(2)=62675
x=5√2507
x=250.35
Answer:
250.35 yards
Step-by-step explanation:
Use the pythagorean theorem to find the height.
[tex]\sqrt{a^{2}+b^{2} }=c[/tex]
Algebraically change the equation to equal to b.
[tex]\sqrt{c^{2}-a^{2} }=b[/tex]
[tex]\sqrt{330^{2}-215^{2} }=b[/tex]
b=250.35 yards
Which equation is correct regarding the measure of ZMNP? O MZMNP = {(x - y) MLMNP = {(x + y) O MZMNP = {(z + y) O MZMNP = {(z-Y)
Step-by-step explanation:
It was correct on edge 2021
The equation that is correct regarding the measure of <MNP is 1/2(x-y)
Circle geometryIn order to determine the measure of m<MNP, we will use the theorem shown below;
The angle at the vertex is half the difference of angles at the intercepted arcs.
The angle at the vertex = m<MNP
angle a the arcs are x and y
Hence;
m<MNO = 1/2 (x - y)
Hence the equation that is correct regarding the measure of <MNP is 1/2(x-y)

I am a bit confused, this is solving systems of equations by elimination.
Answer:
y = -4
x = -2
Step-by-step explanation:
1. Approach
To solve a system by the process of elimination, one wants to manipulate an equation such that when one adds the equations in a system, one of the variables cancels out. The easiest way to do this is to select a variable, then find the LCM (least common multiple) of the two coefficients of the selected variables. Then multiply each of the equations by the respect factor that is needed to get the coefficient of the variable to the LCM. In the event that the cofficients do not have inverse signs, multiply one of the equations by (-1). No all that is left is to add the equations, use inverse operations to solve for the other variable, then back substitute to find the value of the selected varibale.
2.Set up the process
3x - 2y = 2
5x - 5y = 10
Selected variable; x
LCM of the coefficents (3, 5) = 15
Multiply the first equation by 5, and the second by 3
(3x - 2y = 2) *5
(5x - 5y = 10)*3
Resulting system
15x - 10y = 10
15x - 15y = 30
Now, multiply the first equation by (-1) to make the coefficents additive inverses
(15x - 10y = 10) (-1)
15x - 15y = 30
-15x + 10y = -10
15x - 15y = 30
3. Solving
Add the two resulting systems,
-15x + 10y = -10
15x - 15y = 30
_____________
-5y = 20
Inverse operations
-5y = 20
/-5 /-5
y = -4
Back solve
3x - 2y = 2
(3x) - 2(-4) = 2
Simplify,
3x + 8 = 2
Inverse operations,
3x + 8 = 2
-8 -8
3x = -6

Step-by-step explanation:
The transformations are ...
(x, y) ⇒ (-y, x) . . . . 90° rotation
(x, y) ⇒ (-x, -y) . . . . 180° rotation
(x, y) ⇒ (y, -x) . . . . 270° rotation
Each successive rotation is a 90° rotation from the previous one. This makes writing the formulas in a spreadsheet really easy. The attached shows the transformed coordinates.

an employee at an arcade determined he could use the equation y=50-2x to predict the number of tokens a guest has,y, based on the number of minutes, x, the guest has been at the arcade. what is the meaning of the slope of the equation.
Answer:
The rate at which how many tokens a person loses per minute.
Step-by-step explanation:
If we move around the terms in the equation to fit standard form, it will be easier to determine the slope.
y = 50 - 2x
y = -2x + 50
We know that the slope is the coefficient of the x variable, so m = -2 or [tex]\frac{-2}{1}[/tex].
Since the slope is negative, we know that the line will go down as x increases. Since the slope is multiplied by the number of minutes x, we know that the slope represents the typical rate at which a guest spends tokens per minute. In simpler words, how many tokens a person loses every minute.
