Answer:
403.33 kilometros
Step-by-step explanation:
De la pregunta anterior:
6 litros = 110 kilómetros
22 litros = x
Cruz multiplicar
6 litros × x = 22 litros × 110 kilómetros
x = 22 litros × 110 kilómetros / 6 litros
x = 403.33 kilometros
Así, 22 litros recorrerán 403.33 kilómetros
Let x be ml of 5% soln.
let 500-x be ml of 25% soln.
.
x*.05=.05x
(500-x)*.25=125-.25x
500*.20=100
.
.05x+125-.25x=100
-.2x=-25
x=-25/-.2
x=125 ml of 5% soln.
500-x=375 ml of 25% soln.
.
Check:
125*.05= 6.25
375*.25=93.75
