John had 80 filers to post around town. last week, he posted 1/4 of them. this week, he posted 3/5 of the remaining filers. how many filers has he still not posted?

24 fliers

Step-by-step explanation:

he had 80 to begin with so last week if he posted 1/4 of them he would have 3/4 left and

3/4 * 80 = 60

and then if he posts 3/5 of the 60 remaining fliers he would have 2/5 left over and

2/5 * 60 = 24

so your answer is 24 fliers

24 fillers

Step-by-step explanation:

he had 80 to begin with so last week if he posted 1/4 of them he would have 3/4 left and

3/4 * 80 = 60

and then if he post 3/5 of the 60 remaining filers he would have 2/5 left

2/5 * 60 = 24

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
