−2x−(−5−4x)=−5(2x−7)

hoa [83]

Answer:

x = 2.5

Step-by-step explanation:

- 2x - ( - 5 - 4x ) = - 5 ( 2x - 7 )

- 2x + 5 + 4x = - 10x + 35

- 2x + 4x + 10x = 35 - 5

12x = 30

x =  $\frac{5}{2}$  = 2.5

Check the answer:

L.H.S. = - 2(2.5) - [ - 5 - 4(2.5) ] = 10

R.H.S. = - 5 [ 2(2.5) - 7 ] = 10

in the following ordinary annuity interest is compounded with each payment and the payment is made at the end of the compounding

RSB [31]

Answer: $59313.58

Step-by-step explanation:

Formula to find the accumulated amount of the annuity is given by :-

$FV=A(\frac{(1+\frac{r}{m})^{mt})-1}{\frac{r}{m}})$

, where A is the annuity payment deposit, r is annual interest rate , t is time in years and m is number of periods.

Given : m= $2000 ; m= 1 [∵ its annual] ; t= 10 years ; r= 0.06

Now substitute all these value in the formula , we get

$FV=(4500)(\frac{(1+\frac{0.06}{1})^{1\times10})-1}{\frac{0.06}{1}})$

⇒ $FV=(4500)(\frac{(1.06)^{10})-1}{0.06})$

⇒ $FV=(4500)(\frac{0.79084769654}{0.06})$

⇒ $FV=(4500)(13.1807949423)$

⇒ $FV=59313.5772407\approx59313.58 \ \ \text{ [Rounded to the nearest cent]}$

Hence, the accumulated amount of the annuity= $59313.58
