Nicki has 30 pencils. for every green pencil, she has 5 purple pencils. how many pencils of of each color could she have
Hatshy [7]

Answer:


Step-by-step explanation:


(1) P = 5G


(2) G + P = 30


Substituting (1) into (2) gives:


G + 5G = 30


6G = 30


G =5


So there are 5 green pencils.


Now using that in (1) gives us P = 5 x 5 = 25


So there are 5 green pencils and 25 purple pencils.

Alex_Xolod [135]
I'm assuming the the numbers coming after the variables are meant to be exponents, and if I'm wrong just let me know

-3x^4 - 2x^3 + 3x^2 + 3x^4 - 4x^3 + x^2, rearrange to have like terms in order
-3x^4 +3x^4 - 2x^3 - 4x^3 +3x^2 + x^2, now simplify
                0    -6x^3 + 4x^2
