Answer:

u = 94

Step-by-step explanation:

First multiply both sides of the equation by 2.

\frac{u-82}{2} ·2 = 6·2

u - 82 = 12

Then add 82 to both sides of the equation

u - 82 + 82 = 12 + 82

This gives you your answer.

Hope this helps!

Luden [163]
Well 5=5
and 37/40
hmm, try to get that 40 into an nice number that is multiplule of 10
if we divide top and bottom by 4 that would work
( \frac{37}{40})( \frac{ \frac{1}{4} }{ \frac{1}{4} })= \frac{9.25}{10}
9.25/10=92.5=100=925/1000=925 thousandths=0.925

so the decimal would be 5.925
