How to solve 3x+7=2x+1 using Dcmam​
anyanavicka [17]

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.

Suppose you have $1,950 in your savings account at the end of a certain period of time. You invested $1,700 at a 6.88% simple an
Licemer1 [7]

Answer:

He invest for 2 years.

Step-by-step explanation:

Given : Suppose you have $1,950 in your savings account at the end of a certain period of time. You invested $1,700 at a 6.88% simple annual interest rate.

To find : How long, in years, did you invest your money?

Solution :

Applying simple interest formula,

A=P(1+r)^t

Where, A is the amount A=$1950

P is the principal P=$1700

r is the interest rate r=6.88%=0.0688

t is the time

Substitute the values in the formula,

1950=1700(1+0.0688)^t

\frac{1950}{1700}=(1.0688)^t

1.147=(1.0688)^t

Taking log both side,

\log(1.147)=\log ((1.0688)^t)

Applying logarithmic formula, \log a^x=x\log a

\log(1.147)=t\log (1.0688)

t=\frac{\log(1.147)}{\log (1.0688)}

t=2.06

Approximately, He invest for 2 years.
