The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution. what amount of each solution does she need to use?

Volumes of 2% Solution = 5 ml

Volumes of 10% Solution = 5 ml

Simultaneous Linear Equations could be solved by using several methods such as :

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

Let:

Volumes of 2% Solution = x

Volumes of 10% Solution = y

Total Volume = 10 ml

→ Equation 1

The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution.

→ Equation 2

Equation 1 - Equation 2:

Volumes of 2% Solution = 5 ml

Volumes of 10% Solution = 5 ml

answer: i think it is (1,-2)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
