The expression that she can use is 1/6 x 1/5
I hope this can help :)
There are an infinite number of solutions, so I don't plan to list them all.
I'll list two of them, and then describe how to get all of the rest.
You said that <u>2cos(x) - 1 = 0</u>
Add 1 to each side: 2cos(x) = 1
Divide each side by 2: cos(x) = 1/2
The angles whose cosine is 1/2 are 60 degrees, 300 degrees,
and any multiple of 360 degrees added to either of those.
Answer:
x<−2
Step-by-step explanation:
−2x>4
Step 1: Divide both sides by -2.
−2x
−2
>
4
−2
x<−2
Answer:
x<−2
Answer:
= ![z+\frac{1}{5}](https://tex.z-dn.net/?f=z%2B%5Cfrac%7B1%7D%7B5%7D)
Step-by-step explanation:
AS we can see in the figure that a beam or a rod is balanced by a square on right side
while on the left side we have a smaller square and a triangle
Suppose the values written inside it are the weights of the shapes which are making it stable
So
Total on RHS = Total on LHS
Now Total on RHS = Value of bigger square
= ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
Total on LHS = Value of smaller sqaure + Value of triangle
= ![\frac{1}{5}+z](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%2Bz)
Now we know to make this image a balanced one as shown n the figure
Total on RHS = Total on LHS
putting values gives us
= ![\frac{1}{5}+z](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%2Bz)
which is the required equation
Answer:
y= z-3x/4
Step-by-step explanation:
4y=z-3x
y=z-3x/4
