11:19. you would put 11 first to represent the girl and 19 by adding 11 and 8 to represent the total number of students
0.8km = 800m
On Sunday, Li ran farther. 80m farther
800m - 720m = 80m
What you would do is that you would use the y=mx+b linear equation
m=5
x=-1
y=-3
b=?
hence, you must solve b to have the equation
-3=(5)(-1)+b
-3=-5+b
-3+5=b
2=b
therefore the equation is
y=5x+2
for standard form you just move everything to equal 0 because there is no fraction next to the x
thus
-5x+y-2=0
Answer:
first find the diameter 3x2=6
6 is the diameter multiply the diameter x 3.14
