#x=1.5#

Explanation:

what you want to do here is convert the words into variables and place them correctly into an equation. We know that 20 is a definite and are told how big it is (5 more than 10 of a specific number). since we don`t know the decimal number, we will call that #x#.

construct your equation as such:

#20=5+10x#

and then solve for #x#

subtract 5 from both sides

#15=10x#

divide both sides by 10 to isolate #x#

#1.5=x# or #x=1.5#
