A chemist is mixing a 30% salt solution with a 15% salt solution to make 30 L of a new solution that will contain 20% salt. How much of each of the original solutions should the chemist use?

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

what do you mean by fog

step-by-step explanation:

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
