Answer:
Since, Robin is twice as old as Earl,
Thus, the ratio of the age of robin and earl = 2 : 3
Let the age of robin = 2x and the age of earl = 3x
Where x is any number,
According to the question,
3×Age of Adam = 2x + 6
Age of Adam = 1/3(2x+6)
Also, Age of Adam = Age of earl - 8
⇒ 1/3(2x+6) = 3x - 8
⇒ 2x + 6 = 9x - 24
⇒ -7x = - 30
⇒ x = 30/7
Hence, the age of Robin = 2x = 2×30/7 = 60/7 years
The age of Earl = 3x = 3×30/7=90/7 years
The age of Adam = 34/7 years
Answer:
84 months
Step-by-step explanation:
I × 100 = P × R × T
I = interest = $245
P = principal = $1750
R = rate = 2%
T = time(in years) = ??
245 × 100 = 1750 × 2 × T
24500 = 3500T
24500/3500 = T
7 = T
To convert the time to month:
7 × 12 = 84 months
Answer:
a < 42
Step-by-step explanation:
Question : 4a + 9a - 6a < 42
Answer :
4a + 9a - 6a < 42
Combine like terms.
13a - 6a < 42
7a < 42
Divide both sides by 7.
a < 42
