a laboratory technician is developing cleaning solution that will remove stains from clothes. the technician mixes a 20% acid solution with a 5% acid solution. how much of each solution to the nearest millimeter is needed to make 150 milliliters of a 15% acid solution. Set up a system of equation for the given situation. You do not need to solve these.

x=0

step-by-step explanation:

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones

add them

step-by-step explanation:

idk you did not give the options or numbers so you cant solve it

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
