9. write the numbers in order from least to greatest. 3,920 392 3,092 923
10. draw what comes next in the pattern. ○○□○○□○ __ __

Explanation:

Step1: Identify addition property

The formula $(a + b)+c=a+(b + c)$ represents the associative property of addition. So for $(7 + 5)+4 = 7+(5 + 4)$, the property is associative property.

Step2: Perform subtraction

$939118-5426 = 933692$.

Step3: Write number in standard - form

One hundred eleven thousand, six hundred thirty - six is written as 111636 in standard form.

Step4: Calculate number of legs

Since each dog has 4 legs, for 4 dogs, the number of legs is $4\times4=16$.

Step5: Convert units

Since 1 cm = 10 mm, then 7 cm = $7\times10 = 70$ mm.

Step6: Perform division

$48\div5 = 9.6$.

Step7: Round number

To round 65470 to the nearest thousand, look at the hundreds digit. The hundreds digit is 4. Since 4 < 5, we round down. So 65470 rounded to the nearest thousand is 65000.

Step8: Find pattern

The pattern is increasing by 11 each time. So the next two numbers are $222 + 11=233$ and $233+11 = 244$.

Step9: Order numbers

Comparing the numbers 3920, 392, 3092, 923: 392 < 923 < 3092 < 3920.

Step10: Identify pattern

The pattern is two circles followed by one square. So the next two shapes are $\bigcirc\bigcirc$.
