I think it's 12x.
I'm not a 100% sure though, but I hope this helps. =^D
The answer is x=4.
set the equations up: 8x-5=6x-3
Subtract 6x from one side and then the other side 2x-5=3
Add 5 from one side and then the other 2x=8
Divide 2 on each side which gets you x=4
3.9*10 = 39 then that to the 20 power is 6.626621133E31
Hope this helps!
Answer:
$14.08
Step-by-step explanation:
$16.95 * 22% = $3.729
$16.95 - $3.729 = $13.221
^ to find the sale price of the item
$13.221 * 6.5% = $0.859
$13.221 + $0.859 = $14.08
^ to add on sales tax to the sale price
