Answer:
64
Step-by-step explanation:
He will run 30 laps in 60 minutes because 10 times 3 and so if you divide 20 by 10 then he runs one lap in 2 minutes so 2 times 32 is 64 so it will take him that long
40 prizes were dolls : divide 64 by 8 and you get 8. then multiply 8 by 5 and get 40
<span>Since you already have the equation in y = mx + b form, which is called the slope-intercept form, with m = slope and b = y-intercept, you can graph it easily with that information. The 3 is the y-intercept. That means point (0, 3) is where the line crosses the y-axis. Plot that point first. The slope, m = -(1/5). The slope is the rise (up or down) over the run (left or right), or rise/run. -(1/5) can be thought of (-1)/5 or as 1/(-5). Both ways are correct and work. After plotting (0, 3), using m = (-1)/3, start at (0, 3) and count one unit down, and three to the right. That's a second point on your graph. If you want a third point, you can go back to the original point, (0, 3), and now use the slope as 1/(-5). That is, from (0, 3), go 1 unit up and 5 to the left. That is a third point. Now draw a line through all three points. </span>I hope that this is the answer that you were looking for and it has helped you.
