It is a tricky question .Only hard part is understanding the word problem and then converting it into numbers. Let us concentrate on the problem now.
Let us assume the unknown number = x
The coming to the equation part, we get
6(2 - x) = 10
12 - 6x = 10
-6x = 10 - 12
-6x = -2
x = 2/6
= 1/3
So the unknown number is 1/3. I hope i have solved the question to your satisfaction and in future you can do this type of problems by yourself.

A piece of string is 3-5 m long. Joe cuts three pieces from it,

jasenka [17]

Note: <em>It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.</em>

Answer:

140 cm of the original piece is left after Joe cuts three pieces.

Step-by-step explanation:

Given the piece of string

3.5m

As we know that

3.5m = 350 cm

so the length of a piece of string = 350 cm

As joe cuts three pieces from it, and each 70 cm long.

so the total length of three pieces which were

cut by joe = 70cm + 70cm + 70cm = 210 cm

So, subtracting the total length of the three pieces that were cut from the total length of the string:

350 cm - 210 cm = 140 cm

Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.

Answer:

Magnitude and Direction is 928 and 44

Step-by-step explanation:

For a Vector w = (x)i+(y)j

The Magnitude of w $=\sqrt{x^{2} +y^{2} }$

and the Direction of w $=tan^{-1}(\frac{y}{x} )$

So for our Question , w = - 168i - 160j

Then -4w = -4 (- 168i - 160j) = (-4*-168)i +(-4*-160)j = 672i + 640j

Then the Magnitude of -4w = $\sqrt{672^{2} +640^{2} } =928$

and the Direction of -4w = $tan^{-1}(\frac{640}{672} )=tan^{-1}(\frac{20}{21} )=44$ ( to the nearest whole number)

Hope it Helps:)
