Answer:

x=8

Step-by-step explanation:

First we know that 14x +1 and 11x-21 are supplementary angles because they add to 180 degrees. That is the given. Now we need to make an equation.

(14x+1) + (11x-21) = 180

Simplify the equation

25x -20 =180

Addition property of equality

25x =200

Division property of equality

x =8

500 principal earning 3% compound monthly, after 10 years.
mamaluj [8]

Answer:

D. $674.68

Step-by-step explanation:

We will use the well known equation for compound interest

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

Where

  • A is the final total
  • P is the principal amount (starting total)
  • r is the interest rate as a decimal
  • n is the number of times the interest is compounded each year
  • t the number of years

Plugging in what we know from the question:

A = 500(1+\frac{0.03}{12})^{12 \times 10}\\A = 500(1.34935355)\\A = 674.68

So the answer is D.

Hope this helps!
