The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
Answer:

Hope this helps
Multiply the first equality by 3/2 and you get the second
There are thus an infinite number of solutions : x can be any number and y=2-3x/4
Answer:
-6
Step-by-step explanation:
X= 20
1.8x +12=48
48-12 = 36
36/1.8 = 20
