nilai dari 5+(-2) +(-7) adalah?
Answer (3)
10 litres ;)
1/10 x 3/10 = 4/100 5/10 x 5/10 = 25/100
1/10 x 5 = 5/10 (3/10 divided by 3) x5 = 5/10
5y = 5x/3 15y = 5x <-- 20 altogether
40 divided by 20 = 2
2x5 = 10litres 2x15 = 30litres
(Sorry it's written really weirdly, I can't type anything on my phone x'D )
To create 40 liters of a 25% acid solution, Jerry needs 30 liters of the 30% acid solution. He will also need 10 liters of the 10% acid solution. The calculations involve setting up equations based on the total volume and concentration of the acid in the solutions.
