Use a proportion to find the legth of side x for the pair of similar figures below
PtichkaEL [24]

Answer:

Yes, 30.8 is the value of x. I also double-checked by plugging 30.8 into the right side as well.

14/10 = 1.4

30.8/22 = 1.4.

Therefore, because both sides equal 1.4 when you solve with 30.8 plugged in, it must be correct.

find the sums.does the order of the addends matter in an addition sentence? what property is this. -5+6= 6+(-5)=
azamat

In this question we will be using Commutative Law of Addition which is as follows:

The Law that says you can swap numbers around and still get the same answer when you add.

a+b =b+a

where a and b are addends.

Using this law, we can clearly see that order of addends does not matter at all in addition.

Now adding -5+6, we get 6-5 which is equal to 1

Answer is 1
