For #16, it can be assume that the two angles are linear, so set them both equal to 90 (9x+x-10=90) and solve for x. Once you have x, plug it into the equations to find the measure of both angles. If both your final answers are added, they should equal 180. If not, go back and try to find where you messed up.

Answer:
$1,200
Step-by-step explanation:
Let x be the amount of money deposited in the mutual fund. The interest earned by that investment can be determined as the amount deposited times the interest rate:

The value the second deposited can be determined as x+$2,400 and its interest earned is defined in the same manner as the first deposit's:

The total interest on both investment equals the sum of both interests:

$1,200 were invested in the mutual fund.
