If 2x + 2x + 2x = 12 then what is the value of x in 2x – 1 3

Misha Larkins [42]

If 2x+2x+2x=12, then 6x=12 so x=2. x will be 2. Even in 2x-13. ;-)

The value of 2x-13 with x=2 is 4-13 = -9, but that's another question, isn't it?

Oxana [17]

Answer:

time is 6.76 years

Step-by-step explanation:

given data

amount = $150

payment = $100

rate r = 6% = 0.06

to find out

time period t

solution

we know it is compounding continuous

so we will apply here formula that is

amount = payment × $e^{rt}$ ..........1

put here all value we get

amount = payment × $e^{rt}$

150 = 100 × $e^{0.06t}$

take ln both side

ln 1.5 = $e^{0.06t}$

0.40546 = 0.06t

t = 0.40546 / 0.06

t = 6.76

so time is 6.76 years
