Answer:
1/9x+1/9y-1/9z
Step-by-step explanation:
The given equation can be written as w = x/9 + y/9 + z/9.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given the linear equation,
w = 1/9 (x + y + z)
We have the distributive property which states that,
For any three numbers, p, q and r, p (q + r) = (p q) + (p r)
So applying distributive rule in the expression given, we get,
w = (1/9 x) + (1/9 y) + (1/9 z)
w = x/9 + y/9 + z/9
Hence the given linear equation w = 1/9 (x + y + z) can be written as w = x/9 + y/9 + z/9.

If
[tex] \cos(330°) = \frac{ \sqrt{3} }{2} [/tex]
Then prove that:
[tex] \cos(165°) = - \frac{ \sqrt{3} + 1}{2 \sqrt{2} } [/tex]
Please help me!
Answer: see proof below
Step-by-step explanation:
Given: cos 330 = [tex]\frac{\sqrt3}{2}[/tex]
Use the Double-Angle Identity: cos 2A = 2 cos² A - 1
[tex]\text{Scratchwork:}\quad \bigg(\dfrac{\sqrt3 + 2}{2\sqrt2}\bigg)^2 = \dfrac{2\sqrt3 + 4}{8}[/tex]
Proof LHS → RHS:
LHS cos 165
Double-Angle: cos (2 · 165) = 2 cos² 165 - 1
⇒ cos 330 = 2 cos² 165 - 1
⇒ 2 cos² 165 = cos 330 + 1
Given: [tex]2 \cos^2 165 = \dfrac{\sqrt3}{2} + 1[/tex]
[tex]\rightarrow 2 \cos^2 165 = \dfrac{\sqrt3}{2} + \dfrac{2}{2}[/tex]
Divide by 2: [tex]\cos^2 165 = \dfrac{\sqrt3+2}{4}[/tex]
[tex]\rightarrow \cos^2 165 = \bigg(\dfrac{2}{2}\bigg)\dfrac{\sqrt3+2}{4}[/tex]
[tex]\rightarrow \cos^2 165 = \dfrac{2\sqrt3+4}{8}[/tex]
Square root: [tex]\sqrt{\cos^2 165} = \sqrt{\dfrac{4+2\sqrt3}{8}}[/tex]
Scratchwork: [tex]\cos^2 165 = \bigg(\dfrac{\sqrt3+1}{2\sqrt2}\bigg)^2[/tex]
[tex]\rightarrow \cos 165 = \pm \dfrac{\sqrt3+1}{2\sqrt2}[/tex]
Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE
[tex]\rightarrow \cos 165 = - \dfrac{\sqrt3+1}{2\sqrt2}[/tex]
LHS = RHS [tex]\checkmark[/tex]

5. A cargo plane weighed 500,000 pounds. After the first load was taken off, the airplane weighed 437,981
pounds. Then 16,478 more pounds were taken off. What was the total number of pounds of cargo
removed from the plane? Is your answer reasonable? Explain.
Answer:
A total of 78,497 pounds of cargo was removed from the plane.
Step-by-step explanation:
I got my answer by subtracting 437,981 from 500,000 to get 62,019. After, I added the additional 16,478 pounds that were taken off after to get my total of 78,497. My answer is reasonable because after double-checking with my calculator, I noticed I did not make any mistakes and my answer checked out, therefore validifying my answer. Hope this helps and have a good rest of your day/ night :)

Renee had a box of cupcakes, of which she gave 1/2 to her friend Juan. Juan gave 3/4 of his share to his friend Elena. What fractional part of the original box of cupcakes did Elena get?
Answer:
3/8
Step-by-step explanation:
There are 8 cupcakes. Juan gets 4 and there are 4 left. Elena gets 3 out of the 4 that are left. Since there were 8 she got 3 out of the total (8) cupcakes. I used those specific number because that is the most simplified numbers.

in how many year will rs 8000 amount to rs 13824 at 20% per annum interest compounded annually? please please help me out
Answer :-
3 yearsstep by step explanation:-
Let the time be x
principal = rs 8000
Amount = rs 13824
rate = 20% p.a
A = P(1+r/100)^n
13824 = 8000 ( 1 + 20/100)^n
=> 13824/8000 = (120/100)^n
=> 13824/8000 = (24/20)^n
=> (24/20)³ = (24/20)^n
=> 3 = n
=> n = 3 years

5(x – 2) = 30
Distribute:
5x - 10 =30
Add 10 to both sides:
5x = 40
Divide
x=8
Check your work:
5(8 - 2) =30
5(6) =30
5 * 6=30
30=30!

Lines 8 and T are parallel. Find value of X
There are multiple answers!!
A 130
B 50
C 90
D 140
Answer:
The answer is B.
Step-by-step explanation:
Given that vertically opposite angles are the same so the inner angle of the triangle is 40°.
Next, you have to find the other angle of the triangle. Assuming that total angles in a triangle is 180° so you have to subtract :
180° - 40° - 90° = 50°
So the value of x is 50°.

Step-by-step explanation:
Translation 12 units down puts each point 12 units lower on the graph than the position where it is currently shown. Segment RS is now shown on the line y=9. It will be translated straight down so it appears on the line y = 9-12 = -3.
Similarly, T has a y-coordinate of 2. Translated down 12, it will have a y-coordinate of y = 2-12 = -10.
The x-coordinates of all of the points remain the same.
The translation is shown in the attachment.
