Answer:

Choice B) {-21, -7, 7, 21}

Step-by-step explanation:

The multiples of 7 are: 0, 7, 14, 21, 28, 35, ... both the positive and negative versions of each number. Erase the even numbers in that list to end up with 7, 21, 35, ...

Choice A fits the description, but there are items missing, namely -7 and 7. So this answer choice is crossed off the list

Choice B has both odd numbers and multiples of 7 listed. Every number is listed. This is why this is the answer.

Choice C has multiples of 7, but these are even numbers. We can cross it off the list.

Choice D is a similar story to choice C, though it has some odd numbers in this list.

Explain how you can use place value patterns to describe how 50 and 5000 compare

salantis [7]

The place value pattern is a system of patterns of tens in which every place value is ten times the value on its right. The place value pattern system is used to <span>write numbers that are 10 times as much as or 1/10 of any given number.
The place values in the pattern are: ones, tens (10*ones), hundreds (10*tens), thousands (10*hundreds),...
So, 50 = 5 tens
5000= 5 thousands, 0 hundreds, 0 tens, 0 ones

So, 5000 > 50</span>
