What is a reasonable estimate for -3/2x (-5 1/4)
Leona [35]

To estimate, you should round some of the numbers to the closest number (rounding up or down).  It will be more accurate the less you round. In this problem, we should round -5 1/4 to -5 since it is the closest. -5*-3/2 = 7.7. You will end up with -3/2x (-5 1/4) ≈ 7.5x

≈ means approximately equal.

Explain why 2n+1 must be an odd number
Lorico [155]
If is an integer (a whole number), then the expression represents an even number, because even numbers are the multiples of 2. The expressions 2 n − 1 and 2 n + 1 can represent odd numbers, as an odd number is one less, or one more than an even number.
