Answer: 1/20 (fraction) or 0.05 (decimal)
Step-by-step explanation:
first i like to make them a decimal so its easier.
1/4 = 0.25
1/5 = 0.2
multiply 0.25 and 0.2 = 0.05
make 0.05 a fraction
1/20
simplify. (it's already in its simplest form)
the answer is 1/20 as a fraction or 0.05 as a decimal.
(i dont know which one ur teacher wants u to do fraction or decimal?)
e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
Answer:
15
Step-by-step explanation:
Call the unknown time x.
The mean is the sum of the numbers divided by the number of numbers.
There are 5 numbers.
(8 + 10 + 38 + x + 20)/5 = 18.2
(x + 76)/5 = 18.2
x + 76 = 91
x = 15
Answer:
18%
Step-by-step explanation:
