In his free time, gary spends 8 hours per week on the internet and 11 hours per week playing video games. if gary has five hours of free time per day, approximately what percent of his free time is spent on the internet and playing video games?

Internet: 23% to the nearest percent.

Video games:  31% to the nearest percent.

Step-by-step explanation:

The total free time  Gary has in a week is 7*5 = 35 hours.

The percent of time he spends on the internet = (8*100)/35

= 23% approximately.

Percent of time playing games = (11 * 100)/35

= 31% approximately.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

i think it is c, not positive though
