Megan has 12 star sticker. 1/2 of her stickers are yellow, 1/3 are green, and the rest are blue. what fraction of megan’s star sticker are blue?

The fraction of Megan's blue stickers are 1/6.

Step-by-step explanation:

Given:

Megan has 12 star sticker. 1/2 of her stickers are yellow, 1/3 are green, and the rest are blue.

Now, to find the fraction of stickers which are blue.

Total number of stickers  =  12.

Number of red stickers are =

                                              =

Number of green stickers are =

                                                  =    

Number of blue stickers are =

                                               =

Now, to get the fraction of stickers we divide the number of blue stickers by the total number of stickers:

Fraction of blue stickers =

                                         =

Therefore, the fraction of Megan's blue stickers are 1/6.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
