Answer:
5.5 pt or 5 1/2 pt
Step-by-step explanation:
A pint is half of a quart, so multiply 2 3/4, or 2.75 by 2, and you'll get your answer. If
Let's form the difference of the two expressions and see what we can learn.
(2y -x) -(2x -y) = 2y -x -2x +y = 3y -3x = 3(y -x)
Since y > x, this is positive, so 2y -x is greater than 2x -y.
Since 1 pound is $3.09, 4.5 pounds will be:
It says to round to nearest hundredth, so your answer is $13.91.
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
Answer:
-4432.5 m . . . or . . . -4.4325 km
Step-by-step explanation:
You can use the formula for average velocity, fill in the given values, and solve for displacement.
average velocity = displacement/time
-98.5 m/s = displacement/(45 s)
Multiply by time:
(-98.5 m/s)(45 s) = displacement = -4432.5 m

Keeping units with the numbers serves as a check on the math. (m/s)·s = m. The units work the same way variables do: they can be multiplied and divided, raised to a power, canceled. If the units of the problem don't work out right, you're probably doing it wrong. (Note, you can only add and subtract numbers that have the same (identical) units--the same rule as for combining like terms.)
