A gardener buys two kinds of fertilizer. fertilizer A contains 60% filler materials by weight and fertilizer B contains 40% filler materials by weight. Together The fertilizers bought by the gardener contain a total of 240 pounds of filler materials. which equation models this relationship, we are X is the number of pounds of fertilizer A and Y is the number of pounds of fertilizer B

answer: 5/2     2 1/2

step-by-step explanation:

5/2              

5 goes into 2 two times so its 2 and 1/2

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
