Dennis_Churaev [7]

Answer:

first, u need to know the formula for compound interest, which is:

A = P(1 + \frac{r}{100})^{n}

where A is the final amount

P- initial amount

r- percent compounded(interest)

and

n- number of years

so

we have

A = 475(1 + \frac{3.8}{100})^{4}

3.8/100 = 0.038

1+0.038 =1.038

1.038^4 = 1.160885573136

475 * 1.160885573136 = 551.4206472396‬

approximately $551.42

7(x−5)−9=334 what is the answer of x
slega [8]

Answer:

\boxed {x = 54}

Step-by-step explanation:

Solve for the value of x:

7(x - 5) - 9 = 334

-Use <u>Distributive Property</u>:

7(x - 5) - 9 = 334

7x - 35 - 9 = 334

-Combine like terms:

7x - 35 - 9 = 334

7x - 44 = 334

-Add both sides by 44:

7x - 44 + 44 = 334 + 44

7x = 378

-Divide both sides by 7:

\frac{7x}{7}= \frac{378}{7}

\boxed {x = 54}

Therefore, the value of x is 54.
