Answer:
Check Explanation
Step-by-step explanation:
In finance, the rule of 70 estimates how long incomes take to double.
(Number of years it takes for income to
double) = 70/(annual percentage growth rate)
a) At 2.8%
N = (70/2.8) = 25.0 years
It will take 25.0 years for incomes to double.
b) At 4.6%
N = (70/4.6) = 15.2 years
It will take 15.2 years for incomes to double.
c) At 6.3%
N = (70/6.3) = 11.1 years
It will take 11.1 years for incomes to double.
d) At 7.8%
N = (70/7.8) = 9.0 years
It will take 9.0 years for incomes to double.
e) At 8.9%
N = (70/8.9) = 7.9 years
It will take 7.9 years for incomes to double.
What fraction is equivalent to the whole number 6?
Well, any fraction which result gives you 6 is a fraction that would fulfill the requirement, I'll give you a few examples so you can grasp the idea:
6 = 6/1 = 12/2 = 18/3 = 24/4 = 30/5 = 36/6 = 42/7 = 48/8 = 54/9 = 60/10
Step-by-step explanation:
Negative four
-4
Equal to x
-4=x
Divided by five
-4=x/5
Plus six
-4=x/5 +6
Interpretation in the picture above
Solution
Multiply through with 5
5×-4=5×x/5 + 5×6 as shown in the second picture
-20=x+30
Collect like terms
-20-30=x
-50=x or x=-50
