Jenya has 12 bills in her wallet. she has a total of $82. if she has twice as many $5 bill as $1 bills, and two more $10 bills than $5 bills, how many of each does she have?

She has 2-1s, 4-5s and 6-10s. 

You can assume that she must have a number of 1s equal to a multiple of 5 with 2 added since that is the only way to get a number ending in 2. Starting with the obvious starter 2, this would work and add to the appropriate total. 

It is true that organism need food. but cells do not need food. the energy required by the cell for various chemical activities is released by mitochondria in the form of atp (adenosine triphosphate). atp is know as energy currency of the cell.hope it
