Answer:
Step-by-step explanation:
When 
, the variable 
will be removed from the equation (
). Therefore, we are left with 
. Thus, when , the given equation has no solutions.
Answer:
The smallest number n could be is 64.
Step-by-step explanation:
35 + 64 = 99
64/8 = 8
= √289 = 17
Answer:
y = 460 miles per hr
x = 500 miles per hr
Step-by-step explanation:
Let the planes be X any
Let their speeds be xmiles/hr and ymiles/hr respectively
x = y + 40 (assuming X is faster by 40miles/hr)
Distance travelled by X to meet Y = 0.75x
Distance travelled by Y to meet X = 0.75y
0.75x + 0.75y = 720 --------1
Put x = y + 40 in eqn 1
0.75(y+40) + 0.75y = 720
0.75y + 30 + 0.75y= 720
1.5y = 690
y = 460 miles per hr
x = 460 +40
= 500 miles per hr
