z ≅ 3 * 10,7 * ≅ 3,21
Firstly, foil 10(p+10) and -5(2p+11):
Next, combine like terms:
Next, add 10p on both sides:
Next, subtract 89 on both sides:
Next, divide both sides by 20 and your answer will be
The number of students that are expected to carry a backpack is = 378

Answer: " 32.5 % " .
________________________________________________
→ " <u> 32.5 % </u> of 60 is 19.5 . "
________________________________________________
Step-by-step explanation:
________________________________________________
What percent of 60 is 19.5 ?
n/100 * 60 = 19.5 ; Solve for "n" ;
60n / 100 = 19.5 .
6n/10 = 19.5 ;
(0.6) n = 19.5 ;
Multiply Each Side of the equation by "10" ; to get rid of the "decimal" on each side ;
10 * (0.6)n = 19.5 * 10 ;
6n = 195 ;
Divide each side of the equation by "6" ;
to isolate "n" on one side of the equation;
& to solve for "n" ;
6n / 6 = 195 / 6 ;
to get:
_______________________________________________
n = 32.5 .

The answer is: " 32.5 % " .
