The average is 4 3/4 km.
you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.
5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19
19 (the total distance ran) divided by 4 (the number of days) = 4 3/4
Answer:
b=130
Step-by-step explanation:
b+(-43)=87
b+(-43+43)=87+43
b=130
Hope this helps. Have a great day, you amazing bean child.
(Yes you are now my bean child. Get over it)
One way to do this is to use ratios
another way is to graph it
if you use ratios then
1:25=5:125
1/25=5/125
1/25=1/25
therefor theya re in same ratios
(x,y)=(1,25)
find (3,y)
1:25 =3:y
1/25=3/y
multiplyh both siddes by y
y/25=3
multiply both sides by 25
y=75
the point is (3,75)
Answer:
Finally, substitute AB = 6 and BC = 18 - 2AC in
AB + AC > BC 3rd Triangle Inequality condition
6 + AC > 18 - 2AC
-12 > -3AC
4 < AC
AC > 4
So putting all three results together
AC < 12, AC < 8, and AC > 4
Since AC is less than 8, it's automatically less than 12,
so we can dispense with AC < 12. So we have:
AC < 8 and AC > 4 which can be combined and written as
4 < AC < 8 [that is, AC is between 4 and 8]
