Answer:
$960
Step-by-step explanation:
price of one month = total expense/ number of month
= 240/3= $80
therefore persons annual expenses = 80*12= $960
Answer:
2a² + a ( or a(2a+1) )
Step-by-step explanation:
(6a²+3a) - (4a² + 2a) (expand parentheses)
= 6a²+3a - 4a² - 2a (group like terms)
= 6a²- 4a²+3a- 2a
= 2a² + a
= a(2a+1)
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
3/5 - 1/7
Find the LCM of 5 and 7 to find equivalent fractions for both fractions
LCM = 35
3/5 = 21/35
1/7 = 5/35
So 21/35 - 5/35 = 16/35
I'm pretty sure that's the simplest form because I can't think of a common factor of 16 and 35 by which to reduce it further.
