Answer:
11 years
Step-by-step explanation:
7200 - 80x = 5000 + 120x
-5000 + 80x -5000 + 80x
2200 = 200x
11 = x
Step-by-step explanation:
Use the Pythagorean Theorem: a^2+b^2=c^2
We can set up the equation like this: 11^2+y^2=61^2
= 121+y^2=3,721
=y^2=3600
= y = 60
What you have to do first is put them both into improper fractions first. 4 1/6 would be 4 time 6 plus 1 which equals 25/6. Next 1 5/6 would be 1 times 6 plus 5 which equals 11/6. Next what you have to do is subtract 25-6 which equals 19. Next you put 19/6. Two ways to answer is to leave it improper or as a mix number. Answer for improper fraction is 19/6. The other way for a mix number is 3 1/6.
