It took you 15 minutes to read 8 pages of your history book. At that rate, how long will it take you to read 10 more pages?

18.75 minutes.

Step-by-step explanation:

Since it takes 15 minutes to read 8 pages, we divide 15 by 8 to get the minutes per page. We get 1.875 minutes per page. Multiply that by 10 minutes and you get 18.75 minutes.

I got 18.75 minutes (Don't judge if this doesn't work, I'm still in Middle School)

Step-by-step explanation:

15/8 = 1.875

1.875 x 10 = 18.75

Hope it helps! (or not I'm very dumb)

(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
