Answer:

x=18

Step-by-step explanation:

\frac{3x}{5} -\frac{4x}{15} =7-1

\frac{9x}{15} -\frac{4x}{15} =6

5x/15=6

5x=90

x=18

so 60% *OF* the 1 liter
( of technically means * in mathematics)
so 
60% * 1 liter
or 0.6 * 1 liter
Now to find the total number of liters of lemon juice and water in the bottle
(0.6*1)+x= 1
(x being the amount of water)

Part B: We can calculate the number of liters of lemon juice that are present in the bottle
60% * 1
0.6 * 1
that is 0.6
So there is 0.6 liters of lemon juice in the bottle

Hope this helps :)

Divided 85 lbs 2 oz by 6? PLEASE HELP its 12:00 am and I can't think right now
Ostrovityanka [42]
1 pound = 16 ounces
So we have 85 lbs and 2 oz, that is if we convert them to ounces:
85(16) + 2 = 1362 oz
so we have 1362 oz total due to the conversion factor stated above, now we only need to divide:
1362/6 = 227
that is 227 oz
or if we want the result in pounds (lbs), we can by dividing again by 16
227/16 = 14.19 lbs
