Well, the above statement is true so it is not the associative properties because they are just switched around.
What is being demonstrated is the commutative property of addition.
If you are taking the cm to km then it would be like this
4.5km*4.1cm= 18.45km
<span>measure of ∠EGF = 1/2( 180 - 50)
= 1/2(130)
= 65
</span><span>the measure of ∠CGF = 180 - 65
= 115</span>
24% decrease
550 - 420 = 130
130/550 = 24%
X = 0.03
Explanation:
Use PEMDAS to answer.
First I distributed 4 into 2 - 2x: 413x - 3 = 8 - 8x
Next, I added 3 from the left side to get x by itself: 413x = 11 - 8x
Next, I added 8x from the right side to get both x's on one side: 421x = 11
next divide 421x into 11: x = 0.03
Hope this helps :)
