Which of the following is not a prime number 263, 1057, 3163, or 157

1 answer:

3 0

This is why the internet was invented so lets use an online math calculator.
Prime means that the only factors are 1 and itself.

Woah look at what I found!
263 is prime
1057 isn't? oh wow. 7 * 151
3163 is prime
157 is prime

Lila read 142 pages on Friday and 168 pages on Saturday. Estimate how many pageslila read on Friday and Saturday combined.

erik [133]

To find the answer, you need to round to the nearest tens. Round 142 to 140 and 1 68 to 160. You know that 1+1=2, and 6+4=10, so 200+100=300 pages read.
