Answer: 30 percent of 20 is 6.
_______________________________________________
Step-by-step explanation:
_______________________________________________
(n/100) * 20 = 6 ?
Solve for "n" .
_______________________________________________
Divide each side of the equation by "20" :
{ (n/100) * 20 } / 20 = 6 / 20 ;
to get:
n/100 = 6/20 ;
↔ 6/20 = n/100 ; solve for "n" ;
Look at the denominators:
20 * ? = 100 ?
100/ 20 = ? ;
100/20 = 5 ;
So, 20 * " 5" = 100 ;
Then 6* 5 = "n" (for the numerator, "n"; in : "n /100" ) ;
→ 6 * 5 = 30 ;
→ n = 30 .

Im pretty sure that is correct
Answer:
6n
Step-by-step explanation:
Hello,
x<y<z (1)
xy=6b (2)
yz=8b (3)
xz=175 (4)
(2)/(3)==>x/z=6/8==>x=3z/4 (5)
(4) and (5)==>3z/4*z=175==>z²=700/3==>z=√(700/3) (6)
(5) and (6)==>x=3/4*√(700/3) (7)
(1) and (7) ==>3/4*√(700/3)<y<√(700/3) (8)
(8)*z==>3/4*√(700/3)*√(700/3)<yz<√(700/3)*√(700/3)
==>175<yz<700/3
