9x+3x-10=3(3x+x)   simplify

9x + 3x - 10 = 9x + 3x

12x - 10  = 12x      subtract 12x from both sides

-10  = 0       and this is impossible, so........no solution exists....!!!!

No, I ask about the normal stress in Y , why its 0 

incorrect. 

the point of intersection is ( 1.75,5 ) 

4x-2=5

4x=7

x=1.75 

this is how to find x .

to find y substitute the value of x in any equation. 

y = 4(1.75)-2 

y = 5 

ab    is all I can tell you

That is the equation for a line in the form y=mx+b    where m is the slope of the line and b is the point where it intersects the y-axis.

IF the point  (3,6) solves BOTH of the equations, it is a common point to both lines.....substitute and see if it does!

\((\frac{2}{5})^4 = \frac{2^4}{5^4} = \frac{16}{625}=0.0256\)

90 comes from T which was calculated earlier in the solution   The shaft (solid)diameter was stated to be 25mm ....or a RADIUS of 0.0125 m    which would be the 'arm' the torque operates through....      J he calculated in the previous step.

I am not sure,   does this answer your question?

~jc 

(2x2x2x2) / (5x5x5x5)   = 16/ 625 = .0256

\(20/30 = 60/x\)

\(x= \frac{30*60}{20}\)

x = 90

so in 60 min he will travel 90 meters 

I agree you are 26 years old and you have to wait 38 years more until you are 64 years old

162.5

25/5 is 5

5x65 is 325

325/2 is 162.5

365....to count the stars that are VISIBLE stars to you at your observer location.....there are MORE visible stars, but you would have to be in a different hemisphere (above or below the Equator) to see all of them

every night as the earth rotates around the sun you will see additional new stars as some of the ones you saw previous become no longer visible....

what is the answer to nsquared+1

infinity

OK.....the SCALE tells you how far things are on the map in 'scaled' fashion....in this case it says every CM on the map is equal to 8 KILOMETERS in the real world.

So, if it is 18 cm on the map it is  18 TIMES 8 KILOMETERS in the real world....  144 km

Sorry.....I misread the scale as 1:18 in my original post....the question say 1cm=8km    I fixed this error and hope it did not confuse you !!

Solveit is right    it is a '1' with 3000 zeroes after it....    pretty big number.....

No, but six is.

Nope.....that's sick.

Awww c'mon......use the calculator !!

1000^1000     is   ( 10^3 )^1000  = 10^3000
