Answer:
x = 2
Step-by-step explanation:
expand the brackets firstly,
so 12x-4 = 20
then add the -4 onto the other side
so 12x = 24
then divide 24 by 12 to get x
so x = 2
The answer would be 9 and 15.
This is because when splitting you could name the two pieces 3x and 5x. You could then add those pieces together (creating 8x) to set it equal to 24 (8x=24). Then solving that equation x=3. You plug x back into the original equations you created so 3x3=9 and 5x3=15.
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)^nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
