Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":

Subtract y from both sides:

Now, substitute "5-y" for "x" in the first equation:

Note that:


Cancel out like terms:

Subtract 25 from both sides:

Divide both sides by -10

Now, substitute this value back into either of the equations to solve for x.

Add 15/2 to both sides:

Now, find the difference:

Pythagoras theoram? use it here!
That is,
H² = 15² + 4²
H² = 225 + 16
H = √241
H = 15.5
You should opt for 15.5
P.S: Best of luck for your test! ;))
Answer:
16 meters basic math
Step-by-step explanation:
Step-by-step explanation:
So the general formula for compound interest is
where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get
Opportunity Loans:




Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

General Loans:




To find the interest we do the same thing we did in the previous problem

Opportunity loans has the least amount of interest after a year
