-13.4 is the answer. And this is simplified form
To write 81/450 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .
<span>
81/450 * 100 = 0.18 * 100 = 18% </span>
81/450 as a percent<span> equals </span><span>18%</span>
I got x=185
0.75(185)-18.50=0.65(185)
120.25=120.25
Anything 5 and up, because when you multiply the by 15, they equal more than 65, making the inequality true.
