Answer: 15.8 .
Step-by-step explanation:
2 x { 6 + [ 12 ÷ (3 + 2)]} - 1 ;
= 2 x { 6 + [ 12 ÷ (5)]} - 1 ;
= 2 x { 6 + [ 12/5 } - 1 ;
= 2 x { 6 + [ 2.4 ] - 1 ;
= 2 x { 8.4] - 1 ;
= (2 * 8.4) - 1 ;
= 16.8 - 1 ;
= 15.8 .
________________________________________
16-6n=20-2n
add 6n to both sides
16=20+4n
subtract 20 from boths ides
-4=4n
divide 4
-1=n
n=-1

Answer:
171.125
Step-by-step explanation:
The greatest common factor: 20x^6y 40x^4y^2 10x^5y^5 is 10x^4y.
20x^6y = 10x^4y*2x^2
40x^4y^2 = 10x^4y*4y
10x^5y^5 = 10x^4y*y^4
