Answer 5 gallons Let x = the amount of 50% alcohol solution to be mixed, then 50% of (x) + 35% of 10 gallons will equal 40% ( x + 10 gallons) x + 10 will be the amount in the final mixture since you start with 10 gallons + the unknown amount x; hence the final mixture will equal the total amount you start to mix with. Hence 50% x + 35% (10 gallons ) = 40% (x gallons+10 gallons) 0.5 x + 3.5 gallons = 0.4x + 4 gallons 0.5 x - 0.4x = 4 gallons - 3.5 gallons 0.1 x = 0.5 gallons 1x = 5 gallons ( multiply both sides by 10) x = 5 gallons ( since 1 x is the same as x) answer So you mix 5 gallons of 50% alcohol solution containing 2.5 gallons of alcohol since 1/2 of 5 gallons = 2.5 gallons

Answer 5 gallons
Let x = the amount of 50% alcohol solution to be mixed, then 50% of (x) + 35% of 10 gallons will equal 40% ( x + 10 gallons)
x + 10 will be the amount in the final mixture since you start with 10 gallons + the unknown amount x; hence the final mixture will equal the total amount you start to mix with. Hence
50% x + 35% (10 gallons ) = 40% (x gallons+10 gallons)
0.5 x + 3.5 gallons = 0.4x + 4 gallons
0.5 x - 0.4x = 4 gallons - 3.5 gallons
0.1 x = 0.5 gallons
1x = 5 gallons ( multiply both sides by 10)
x = 5 gallons ( since 1 x is the same as x) answer
So you mix 5 gallons of 50% alcohol solution containing 2.5 gallons of alcohol since
1/2 of 5 gallons = 2.5 gallons
Bah, relax yata c ma'm ngayon. Good.
The video sound is pretty good, beyond my imagination
Salamat po very much 😊
Thank you so much Mam L.
If possible, kindly keep it in English all through
1 7/8 hrs po maam
Maam bakit nag (10+N) sa 40%?
