if a 35 year old women has averaged 8 hours of sleep each 24 hours how many days of her life has she spent
Masteriza [31]
(8•365)•35 is the correct answer because 8 hrs of sleep each day times 365 days in a year = 2920 hrs slept in one year. Now you must take 2920 and multiply it by the 35 years she has been alive to get 102,200 hrs of sleep.

4x + 5 = 25 x = 2 x = 5 x = 2 x = 7
olchik [2.2K]

Hi there!

Answer:

\huge\boxed{x = 5}

4x + 5 = 25

Subtract 5 from both sides:

4x + 5 - 5 = 25 - 5

4x = 20

Divide both sides by 4:

4x/4 = 20/4

x = 5.
