Y=-a
x=b
a^2x-b^2y/ab=a+b
ax-by=2ab
This is the commutative property of addition
This property is the idea of adding any two numbers in any order you want. For example: 2+3 = 3+2 = 5
In this problem, we have 2.5+12.66 the same as 12.66+2.5
You can this is just the forms basically
Wwwooooooowwwww
hh hhhhhhhhhhhhhhhhh
Answer:
Step-by-step explanation:
speed = s = 3.5 miles / hour
d = 6 miles
t = ?
============
t = d / s
t = 6 / 3.5
t = 1.714 hours
t = 1 5/7 hours
You could figure this out in minutes for 5/7 but it will not make the time any clearer. You will still wind up with a fraction.
