Ответ:
Sierra studied 3 hours
William studied 2 hours
Step-by-step explanation:
jonah studied 6 hours.
He also studied 3 hours longer than sierra meanining sierra studied 3 hours less than 6 hours.
So, 6 hours minus 3 hours is equals to 3 hours.
With that being said, Sierra has studied 3 hours.
Sierra = 3 hours
The question then states that Jonah studied 3 times as many hours as William.
Reminder: Jonah studied 6 hours in total.
This means that jonahs' hours (6 hours) is equals to 3 times williams hours (3x)
6 hours= 3x
x= williams hours
we divide both sides by 3 to see what x is equals to
in other words, we divide Jonahs' hours to see what williams hours are
With that being said, William studied for 2 hours
2 hours = x
Ответ:
Sierra studied for 1 hour longer than William
Step-by-step explanation:
Because Sierra studied for 3 hours and William studied for 2 hours. 3-2=1
Ответ:
n = 27
Step-by-step explanation:
Multiply both sides of the equation by 3
3 x 1/3n = 3 x 9
Reduce the number with the Greatest common factor (gcf) 3
n = 3 x 9
Multiply the numbers
n = 27
