First I would change the descriptions of the numbers into expressions.
first number is n
second number is n + 6
third number is 4n (4 x n)
Then you would insert these expressions into an equation and isolate n.
n + n + 6 + 4n = 144
n + n + 4n = 144 - 6
6n = 138
n = 138/6
n = 23
Lastly, you would plug in this value into all of the expressions.
first number is 23
second number is 23 + 6 = 29
third number is 4(23) = 92
Therefore, the numbers are 23, 29, and 92.
The answer is 9. there are 9 different combinations to choose from.
Answer: x - 30 = 10

x - 30 = 10
x = 30 + 10
x= 40
Answer:
$4956.23 approx
Step-by-step explanation:
Given data
P= $4860
R= 4%
T= 6 months = 0.5 years
Applying the compound interest formula we have
A=P(1+r)^t
Substitute
A=4860(1+0.04)^0.5
A= 4860(1.04)^0.5
A=4860*1.0198
A=4956.228
Hence the balance will be $4956.23 approx
