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

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

what are the things "represented below"?

nobody can if you dont give the choices
