- The expression was rewritten using the commutative law of addition.
- Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots.
- Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.
<h3>What is the
commutative law of addition?</h3>
The commutative law of addition is also referred to as the law of cumulative addition and it states that if two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.
This ultimately implies that, the sum of addends would always be the same (equal) regardless of their arrangement in accordance with the commutative law of addition. Mathematically, the commutative law of addition can be represented using the following formula:
A + B = B + A.
In this context, we can reasonably infer and logically deduce that the given expression was rewritten using the commutative law of addition.
In conclusion, Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

Answer:
0.749m and 2.25m
Step-by-step explanation:
to convert from centimeters to meters, you divide by 100 because there are 100cm in 1m
74.9cm/100= 0.749m and 225cm/100=2.25m
The ratio of girls to boys would be 16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)
It will take 148
hours (In decimal form its 148.66336633)
500500-200200=300300
300300÷2020=148.66336633
Thi answer be 753.6 i wish you good marrow
