A chemist wants to make a 10% solution of fertilizer. How much of a 5%
solution and of a 30% solution should the chemist mix to get 30 L of a 10%
solution?

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

so first lets findout how much she spent so whats 32.00 - x = 9.20

32.00 - 22.75 =9.25. so she spent a total of $22.75 okay now we know the amount she spent. so now u got it from here.

answer: qc and de are congruent

hope i ! : )
