Use the commutative property to create equivalent expressions. which expressions are equivalent to 2.2t + 3.5 + 9.8? check all that apply. 3.5 + 2.2t + 9.8 3 + 2t + 9 2.2 + 3.5 + 9.8t 9.8 + 3.5 + 2.2t 2.2t + 9.8 + 3.5 2.2t + 35.98

The answer is:

(Option 1).

(Option 4).

(Option 5).

The explanation for this answer is shown below:

1. The commutative property of addtion establishes that if you change the order of the addends, the sum will not change.

2. Let's say that and are real numbers, Then they can added them to obtain a result :

3. If you change the order, you will obtain the same result:

4. Therefore, the only options that show the applicaction of this property, are the options shown above.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
