Answer:
<u>equation: 55 + (2x + 3) + 90 = 180</u>
55 + 2x + 3 + 90 = 180
2x + 148 = 180
2x = 32
<u>x = 16</u>

Answer:
P = 2000 * (1.00325)^(t*4)
(With t in years)
Step-by-step explanation:
The formula that can be used to calculated a compounded interest is:
P = Po * (1 + r/n) ^ (t*n)
Where P is the final value after t years, Po is the inicial value (Po = 2000), r is the annual interest (r = 1.3% = 0.013) and n is a value adjusted with the compound rate (in this case, it is compounded quarterly, so n = 4)
Then, we can write the equation:
P = 2000 * (1 + 0.013/4)^(t*4)
P = 2000 * (1.00325)^(t*4)
Answer:
-125/27
Step-by-step explanation:
(-3/5)^-3= 1÷(-3/5)³
=1÷(-3³/5³)
=1÷(-27/125)
=1×(125/-27)
=-125/27
A is the answer I would say
