Remember the divisibility rule for 9. The sum of the digits of the number must be divisible by nine. 
Let the digit be x. Then x+3+5+2+0=x+10 has to be divisible by nine. Recalling that 18=9*2, we note that x=8.

1/8
1 divided by 8
=12.5

Hope you get it right :)

PLEASE HELP ASAP!!!
Dimas [21]

Step-by-step explanation:

5x^2+2x=1

5x^2+2x-1=0

x=-b+/-√b^2-4ac÷2a

x=-2+/-√-2^2-(4×5×-1)÷2×5

x=-2+/+√4--20÷10

x=-2+/-√24÷10

x=-2+√24÷10 or -2-√24÷10

x=-2+4.9÷10 or -2-4.9÷10

x=2.9÷10 or -6.9÷10

x=0.29 or -0.69
