Question

Find the first two equations that are needed to solve the following story problem: How many milliliters of a 5% acid solution and how many milliliters of a 17% acid solution must be mixed to obtain 60 mL of a 13% acid solution? ​

Answer 1

Answer:

Step-by-step explanation:

saw it on chegg

.05x+.17y=.13

x+y=60

Answer 2

The two correct equations are "$0.05 x+0.17 y=0.13$ and $x+y=60$". A further solution is provided below.

According to the question,

Let,

• Quantity of 5% acid solution will be "x".
• Quantity of 17% acid solution will be "y".

Given total acid solution,

= 60 mL

then,

→  $x+y = 60$...(equation 1)

We know that the concentration of mixture = 13%

hence,

→  $5 \ percent \ of \ x + 17 \ percent \ of \ y =13 \ percent (x+y)$

or,

→  $0.05x+0.17y=0.13(60)$

Thus the above answer is correct.
