What is 3x/2+7=13 i don't know how to salve this problun

Julli [10]

your answer is 39.

First you would add 7 and 2 to get 9. From there you would get the equation 3x/9=13.

Then you would multiple by the reciprocal, or 9/1 to cancel out 3x/9.

Then u multiply 9×13 because what u do to one side you have to do to the other.

Your equation should now say 3x=117.

Finally divide by 3 to solve for x.

X=39.

4. James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They

Zinaida [17]

$ 159,744.59 will be in the account after 20 years.

Answer: Option A

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

Need to find out the amount present in the account after 20 years. The formula to find out the future value is,

$\text {Future value}=p \times\left(\frac{\left(1+\frac{r}{n}\right)^{n t}-1}{\frac{r}{n}}\right)$

Here

p : amount deposit monthly =$500

r : rate of interest = $\frac{2.75}{100}$ = 0.0275

n : 12(compound monthly)

t : time =20

By substituting all the given datas in the above equation, we get

$\text { Future value }=500 \times\left(\frac{\left(1+\frac{0.0275}{12}\right)^{240}-1}{\frac{0.0275}{12}}\right)$

$\text {Future value}=500 \times\left(\frac{(1+0.002291)^{240}-1}{0.002291}\right)=500 \times\left(\frac{(1.732)-1}{0.002291}\right)$

$\text { Future value }=500 \times\left(\frac{0.732}{0.002291}\right)=500 \times 319.511=\$ 159,744.99$
