Beatriz started with 16 pencils and gave away x pencils. Ella started with 36 pencils and gave away three times as many pencils as Beatriz did. How many pencils did Beatriz give away, given they had the same number of pencils left? 6 pencils 7 pencils 10 pencils 12 pencils Please help

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
