Convert the mixed number -14/5 into an improper fraction first by multiplying the denominator (5) by the whole number part (1) and add the numerator (4) to get the new numerator. Place the new numerator 9 over the old denominator 5
-9/5x=9 simplify -9/5x
write x as a fraction with a denominator of 1
-(x/1*9/5)=9       -x*9/5=9

-9x/5=9    multiply both sides by 5
-9x=9*(5)
-9x=45
x=-5

- 1 4/5x = 9 (turn the mixed number into an improper fraction)
-9/5x = 9 (now multiply both sides by -5/9 eliminating the -9/5 on the left side)
x = 9 * -5/9
x = -45/9 = -5 <===

Points If a person invests $250 at 9% annual interest, find the approximate value of the investment at the end of 15 years.
AfilCa [17]

Principal Amount = P = $250

Interest Rate = r = 9% = 0.09

Time in years = t = 15 years

Value of investment = A = ?

The formula to calculate the value on investment as a result of annual interest is:

A=P(1+r)^{t}

Using the values in the above formula, we get:

A=250(1+0.09)^{15}\\ \\  A=\$ 910.62

Thus, at the end of 15 years the value of the investment will be $ 910.62.
