Answer: " 15 % " .
_______________________________
→ " 12 is <u> 15% </u> of 80 " .
_______________________________
Step-by-step explanation:
_______________________________
12 = (n/100) * 80 ;
12 = (80n) /100 ; Solve for "n:
Note: 80/100 = (80/10) / (100/10) = (8/10) = 0.8 ;
12 = (0.8)n ;
↔ (0.8n) = 12
Multiply each side of the equation by "10" ; to get rid of the "decimal" ;
10 * (0.8n) = 10 * 12 ;
to get:
_______________________________
8n = 120 ;
Divide each side of the equation by "8" ;
to isolate "n" on ONE SIDE of the equation; & to solve for "n" ;
8n/8 = 120/ 8 ;

to get:
_______________________________
n = 15 .

Answer:
a = 1/64
Step-by-step explanation:
3 + 4 a ^ 1/6 = 5
1. move constant to the right side and change its sign
4 a ^ 1/6 = 5 - 3
2. using <em>a</em><em> </em><em>^</em><em> </em><em>m/</em><em>n</em><em> </em><em>=</em><em> </em><em>n√a^m</em><em> </em><em> </em>transform the expression
4 6√a = 5 - 3
3. Subtract the numbers
4 6√a = 2
4. Divide both sides of the equation by 4
6√a = 1/2
5. Raise both sides of the equation to the power of 6.
a = 1/64
