All you need to do is set the equation for angle b to the equation for angle d and solve for x and then what ever you got for you x value plug it in to one of the tow equations and what ever you get as a final answer is the value of each angle
Answer:
100
Step-by-step explanation:

Answer:
Mode = 22 Median = 22.66* Range = 20
Step-by-step explanation:
So there is actually 3 different types of averages. The most common answer will be the median, thats the one where you add up all the numbers, then subtract by the number of numbers.
Total investment = $10,500
Let x = amount of first investment, and y the amount of the second investment.
First investment:
Interest rate = 9 (1/5)% = 0.092
Earned interest = 0.092x
Second investment:
Interest rate = 9% = 0.09
Earned interest = 0.09y
Total interest after one year is $957.00, therefore
0.092x + 0.09y = 957
or
1.0222x + y = 10633.33 (1)
Also,
x + y = 10500 (2)
Subtract (2) from (1).
0.0222x = 133.33
x = 6000
y = 10500 - x = 4500
Answer:
The first investment is $6,000 at 9 (1/5)% rate;
The second investment is $4,500 at 9% rate.
