Answer:
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a 
by shape. We'll use Pythagorean Theorem to find the diagonal.
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
5x+6y=18
5x=18-6y
x=(18-6y)/5
Use that in the other equation
18(18-6y)/5 - 15y = 36
64.8-21.6y - 15y = 36
28.8=36.6y
.7868=y
Now put that number in for y on the first equation
5x+6(.78) = 18
5x + 4.68 = 18
5x = 13.32
x = 2.66
and y = .78
Answer:
Step-by-step explanation:
Use the formula
where P is the initial investment, r is the interest rate in decimal form, and t is the time in years. Filling in what we are given:
and simplifying a bit:
and a bit more:
A(t) = 5000(1.340095641) so
A(t) = 6700.48
Here is the answer- 297. I hope this helps! I solved this by changing the fractions so that they had the same denominators.
