The number is -6.
Step-by-step explanation:
Variable x = a number
Set up an equation:
3x + 12 = -6

-18 + 12 = -6
-6 = -6

Answer:
3/100
Step-by-step explanation:
convert these measurements into one unit, I am going to do decimals but you can sue fractions or percentages as well.
1/4 is 0.25
2/5 is 0.4
0.12 is 0.12
20% is 0.2
if you add all these up, it equals 0.97
1- 0.97= 0.03
you therefore have 0.03 of the money left over
this as a fraction is 3/100
