I believe they are all false
Let the numbers be x and y.
by the first statement of the question, we get , x + y = 30.,,..(1)
by the second satement, we get , x = y+ y => x=2y... (2)
from equation (2), let us put the value of x in equation (1),
x + y = 30
=> 2y + y = 30
=> 3y = 30
=> y =30/3
=> y = 10
and x=2y => x = 2*10 = 20
in short, the numbers are 10 and 20
Answer:
40
Step-by-step explanation:
for every 8 km do 5 miles then u get 40 miles
So distance areound=circumference=pi times diameter
so
circumference=9753
pi=22/7
subsitute
9753=22/7 time diameter
multipliy both sides by 7/22 to clear fraction
68271/22=diamter
3103 and 5/22=3103.23 ft
answer is 3103.23 feet
