The first one is 4n+7=15, the second one is 1/4(n-15), the third one is 1/4n-15, the fourth one is n/7=4, and the last one is n4+7=15
18% because 20+3=23 and 134-3=131 and so you divide 23/131 and you get 17.55 which rounds up to 18%
You can make a proportion
<em>Cross multiply</em>
8 × 6 = 48
<em>Now, divide 48 by 9</em>
48 ÷ 9 = 48/9
x = 48/9
