3- 2b +4 = 2-7b
3+4 = 2 - 5b
7 = 2 -5b
5 = -5b
-5b /-5 = -1
b = -1
Answer:
C. 2x
Step-by-step explanation:
Let
B's age = x years
A's age = 2 times older than B
= 2 * x
= 2x years
A's age = 2x years
For instance, if B's age is 17 years
Then,
A's age = 2x
= 2(17)
= 34 years old
Hi there
The formula is
A=p (1+r)^t
A future value
P present value 75
R interest rate 0.05
T time
After 1 year the balance is
A=75×(1+0.05)
A=78.75
After 2 years
A=75×(1+0.05)^(2)
A=82.69
After 5 years
A=75×(1+0.05)^(5)
A=95.72
After 20 years
A=75×(1+0.05)^(20)
A=198.99 round
A=199
Hope it helps
