See below

Step-by-step explanation:

4k - 3 = 2k + 5 Given

4k - 3 -2k = 2k + 5 - 2k Addition (added -2k to both sides )

4k - 2k - 3 = 2k - 2k + 5 Commutative (changed the order of the terms)

2k - 3 = 0 + 5 Addition/ Identity

2k - 3 = 5 Addition

2k - 3 + 3 = 5 + 3 Addition (added 3 to both sides)

2k + 0 = 8 Addition

2k = 8 Identity

61% of 180 ?

First, when multiplying percents, you need to convert them to decimals. You convert percents to decimals by multiplying by 100 or moving the decimal two places to the left. Once you convert them to full decimals, you multiply the decimal by the number that you are getting the percentage from

61% of 180⇒.61×180=109.8 

5.1% of 81?⇒.051×81=4.131

 $16 \frac{1}{2}$ of 36?⇒16.5×36⇒.165×36=5.94

81% of 241⇒.81×241=195.21

76% of 600⇒.76×600=456

88% of 680⇒.88×680=598.4

37% of 481⇒.37×481=177.97

19.1% of 380⇒.191×380=72.58

41% of 321⇒.41×321=131.61

33% of 331⇒.33×331=109.23
