<span>PV=NRT</span>If you want to solve that for n, remember that you can multiply or divide the whole equation by any number or expression as long as you do it to both sides. For example, if we divide both sides by R we get
<span><span><span>PVR</span></span>=NRT</span>or<span><span><span>PVR</span></span>=NT</span>after canceling R from both numerator and denominator on the right. Continue the process to solve for N.
9.68 X 10^3. Hope this helped :)
The answer is 0.0055 rounded
The answer is B.red
the reason:
if x=2
-2 (2)+ 5y = 10
-4 +5y = 10
5y = 10+4
5y = 14
y = 2.8
now we have the point (2 . 2.8) which is absolutely on the line -2x + 5y = 10
when we look for it we see that it's on the line b which means line b is -2x + 5y = 10
