63 x 38 = 2394
63 x 10 = 630
600 x 3 = 1800
30 x 3 = 90
1800 + 90 = 1890
63 x 2 = 126
630 - 126 = 504
1890 + 504 = 2394
Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
K=am+3mx
K=m(a+3x)
m=K/(a+3x)
Answer: m=K/(a+3x)
The average speed would be 53 miles per hour, hope this helped, if you need me to explain then here is the way, so all you do is divide 265 by 5 and what I did to help make it faster was split 265 into 250 and 15 so 250 divided by 5 is 50 and 15 divided by 5 is 3 so 50 + 3 = 53!
