<span>So we want to know how many students out of 144 practice martial arts every day if we know that 7/12 practice every day. So lets multiply the numerator and the denumerator with 12. We will get (12*7)/(12*12)=84/144. And we got our answer: 84 out of 144 students practice every day.</span>
Answer: Actual answer is 10x sq root 30
Step-by-step explanation: Factor 4 out of 12 first. sq root 5 (2 sq root 3x) sq root 50
Rewrite using commutative property
2 times sq root 5x sq root 3x sq root 50
use power rule a^ma^n=a^m+n to combine
0.255x = 153
x = 153/0.255
x = 600
