7/8 subtract 1/2 equals. and explain how you got your answer
puteri [66]
3/8 because you find the common denominator
8: 8,16,24,32
2: 2,4,6,8
1/2=4/8
7/8-4/8
So the answer is 3/8
You can try to find the denominator and then change the denominator+numerator.

Solve for x<br> (x/r)+(x/w)+(x/t)= 1
MissTica

<em>x</em>/<em>r</em> + <em>x</em>/<em>w</em> + <em>x</em>/<em>t</em> = 1

<em>x</em> (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) = 1

<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>)

To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, <em>rwt</em> :

<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) • <em>rwt</em> / <em>rwt</em>

<em>x</em> = <em>rwt</em> / (<em>rwt</em>/<em>r</em> + <em>rwt</em>/<em>w</em> + <em>rwt</em>/<em>t</em>)

<em>x</em> = <em>rwt</em> / (<em>wt</em> + <em>rt</em> + <em>rw</em>)

HELP 30 POINTS!!!!!!!!!!!!!!!!!!!!!<br><br><br> Please explain this!!!
finlep [7]

First, multiply the first equation by 3 to get:

3x+3y=-6

Then, add the two equations together to get

8x=16

We can follow that x=2. Plugging in x=2, we get that y=-4.

Therefore, the solution of (2,-4)
