Coefficients are the numbers that come before terms. Each term has a coefficient before it.
Answer:
The speed of the boat in still water is 10 miles / hour
Step-by-step explanation:
The trip there, and the trip back are the same -- 30 miles
Let the rate of the boat = x
Let the rate of the water = y
30 = 2*(x + y)
30 = 6*(x - y)
Divide the top equation by 2
Divide the bottom equation by 6
15 = x + y
<u>5 = x - y </u> Add the equations together.
20 = 2x Divide by 2
20/2 = x
x = 10
If you are ordering rational numbers you are basically doing the same thing a ordering whole numbers. The only difference is that rational numbers are in between whole numbers. Like always, to the left is less and to the right is more. Ex. if 1/8 is to the left of 1/4 you know that 1/8 is less.
That's a beautiful formula by the way.
I can't answer that because there is no other part to the question
