The sum of two numbers is 38. Their difference is 50. What are the numbers?<br><br> 20 POINTS
enot [183]
Let, the numbers = x,y
Now, x + y = 38
x - y = 50, x = 50 + y

Substitute it into first equation,
50 + y + y = 38
2y = 38 - 50
y = -12 / 2
y = -6

Substitute it into first equation,
x - 6 = 38
x = 38 + 6 = 44

So, your final answer is x = 44 & y = -6

Hope this helps!

If the simple interest on $5,000 for 4 years is $1,600, then what is the interest rate?
matrenka [14]

Answer:

0.08, or 8%

Step-by-step explanation:

The appropriate formula is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

We want to calculate r when i, p and t are known.

                                                           i

Solving i = p*r*t for r, we get r = ------------

                                                       p*t

The interest rate in this case is

        $1600

r = ---------------- = 0.08, or 8%

      $5000*4
