Answer:
y = 6
Step-by-step explanation:
Exponential decay formula is Total = starting value x (1- percentage)^ time
Total = 2000(1- 0.0375)^11
Total = 2000(0.9625)^11
Total = 1313.524 km
Rounded to nearest km = 1314 km
Answer:
at least 20 characters is what I need to answer with
11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
