Answer:


Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 = 
Product of 12 and x, (12*x), decreased by 20 =
.
Set both expressions equal to each other and solve for x as shown below:
(equation)
Subtract 12 from both sides


Subtract 4 from both sides


Divide both sides by -6


A = 50% / equally likely
B = less likely / unlikely
C =less likely
D = Impossible
5m-8=3m+8
(Plus the '8' to both sides)
5m=3m+16
(Subtract '3m' from both sides)
2m=16
(Divide by 2)
m=8
920
18 rounded is 20 as the second number is the ten
