How to solve 3x+7=2x+1 using Dcmam​

Mathematics
1 answer:
anyanavicka [17]2 years ago
6 0

Answer:

x = -6

Step-by-step explanation:

3x + 7 = 2x + 1

Subtract 7 on both sides to leave 3x alone

3x = 2x - 6

Subtract 2x on both sides to have X on one side only

3x - 2x = x

x = -6

I'm not entirely sure as to what Dcmam is but there is really not much else you can do to find this value of x, it's as simple as that.

Find how many years it would take for an investment of $3700 to grow to $6000 at an annual interest rate of 6.2% compounded semi
lorasvet [3.4K]

Answer:

  7 years 11 months

Step-by-step explanation:

The future value formula for the value of a principal P invested at annual rate r compounded n times yearly for t years is ...

  FV = P(1 +r/n)^(nt)

For the given numbers, we want to find t:

  6000 = 3700(1 +.062/2)^(2t)

Dividing by 3700 and taking the logarithm, we get ...

  6000/3700 = 1.031^(2t)

  log(60/37) = 2t·log(1.031)

Dividing by the coefficient of t gives ...

  t = log(60/37)/(2log(1.031)) ≈ 7.92 . . . . . years

It will take about 7 years 11 months for the investment to grow to $6000.
