Forty five times nine thousand ninehundred ninety nine is equal to 449,955
To solve for N, nullify 100 by multiplying both sides with 100. The resulting equation will be N = 0.982*100. Multiply 0.982 by 100 and you will get the answer. The N in this equation is 98.2.
Answer:
5.45 hours or 5 hours 27 minutes to nearest minute.
Step-by-step explanation:
We work in rates per hour.
Kevin does 1/10 of the roof in an hour and Sam does 1/12 of the roof/hour.
Now we add to get the equation:
1/10 + 1/12 = 1 / x where x is the time they take to repair the roof working together.
Multiplying through by the LCM 60x:
6x + 5x = 60
11x = 60
x =60/11
x = 5.45 hours.
