25x^2 - 64y^2
The first thing you can do is look for a subtraction sign. The word difference implies subtraction, so you can rule out any expressions that add terms. Secondly, you can look for squares. 17x^2 - 23y^2 is a subtraction expression, but 17 and 23 are not squares. However, 25x^2 - 64x^2 is a subtraction expression and its terms are squares. 25 = 5x5, 64 = 8x8. Hope this helps!
So first thing we have to realise is that we have to make them have equal denominators. So,
.
Now order the fractions....so,
Now we can see why 
is greater than 
but less than 
-3.62 is greater than -29/8
Answer:
Step-by-step explanation:
it is adding or subtrating
If you would like to know the average rate in miles per hour, you can calculate this using the following steps:
420 miles ... 210 minutes
x miles = ? ... 1 hour = 60 minutes
420 * 60 = 210 * x
x = 420 * 60 / 210
x = 120 miles
The correct result would be 120 miles per hour.
