Solve y=5/8b + 10 for b

wolverine [178]

This is quite simply just rearranging for b.

$y= \frac{5}{8}b+10$

$y-10= \frac{5}{8} b$

$b = \frac{y-10}{\frac{5}{8}} = \frac{8(y-10)}{5} = \frac{8y-80}{5}$

Which expression can be used to determine 50% of 42?

Crazy boy [7]

Hey there! :D

Since 50% is half of 100%, it would also be half of 42.

42/2 <== that can be used to determine 50%

42/2= 21

50% of 42 is 21.

You could also use this:

42*.5= 21 <== this also works

I hope this helps!
