At the beginning of year 1, Sam invests $700 at an annual compound interest
Aleksandr-060686 [28]

at the beginning of year 4, only 3 years have elapsed, the 4th year hasn't started yet, since it's at the beginning, so at the beginning of year 4 we can say only 4-1 years have elapsed.

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$700\\ r=rate\to 5\%\to \frac{5}{100}\dotfill &0.05\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=\textit{elapsed years}\dotfill &3 \end{cases}

A=700\left( 1 + \frac{0.05}{1} \right)^{1\cdot 3}\implies A = 700(1+0.05)^3\implies A(4)=700(1+0.05)^{4-1} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill A(n)=700(1+0.05)^{n-1}~\hfill

How to get the answer to 2/3(3x+6)=4x+3 without using distributive property.
Annette [7]

The answer for the given equation is x = 3.5.

<u>Step-by-step explanation</u>:

Given, 2 / 3 (3x + 6) = 4x + 3

Step 1:

Rearranging the given equation by subtracting the right side of the equation to the left side.

                           2 / 3 (3x + 6) - 4x + 3 = 0

Step 2:

Taking out the like terms, the equation becomes

                          (2 / 3) \times 3 (x + 2) - (4x - 3) = 0

                          ⇒   2 (x + 2) - (4x - 3) = 0

Step 3:

Solving the equation for the value of x,

                          ⇒    2x + 4 - 4x + 3 = 0

                          ⇒    -2x + 7 = 0

                          ⇒     -2x = -7

                          ⇒     x = 7 / 2 = 3.5.

Hence the value of x = 3.5.
