Svetllana [295]

The complete question is

Zach has 3/4 hour to play video games. it takes him 1/12 hour to set up the system. Each round of his favorite game takes 1/6 hour. How many rounds can he play

we know that

1) Zach has $3/4$ hour to play video games

Convert to minutes

$1\ hour=60\ minutes$

$(3/4)*60=45\ minutes$

2) It takes him $1/12$ hour to set up the system

Convert to minutes

$(1/12)*60=5\ minutes$

3) Find time available to play video games

$45\ minutes-5\ minutes=40\ minutes$

4) Each round of his favorite game takes $1/6$ hour

Convert to minutes

$(1/6)*60=10\ minutes$

5) Divide the time available to play video games by the time each round of his favorite game

$40/10=4\ round$

therefore

the answer is

$4\ round$

-1/3x-4/3y=-2 1/3x-2/3y=4 using elimination

Minchanka [31]

-1/3x-4/3y=2

1/3x-2/3y=4

First realize that the coefficient of x is -1/3 and 1/3 which can be eliminated with addition

Adding the two equations together gets

-6/3y=6

Simplify

-2y=6

y=-3

Substitute back into original equation

1/3x-2/3(-3)=4

1/3x+2=4

1/3x=2

x=6

Answer

x=6, y=-3

Check answer

-1/3(6)-4/3(-3) =?= 2

-2+4=2

2=2

Done!
