Un químico cuenta con dos soluciones de ácido. Una contiene 15% de ácido puro y la otra 6 %. ¿Cuántos cm3 de cada solución debe usar para obtener 400 cm3 de una solución con 9 % de ácido?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
