Answer:
182 days
Step-by-step explanation:
Given:
Date on which loan is made = March 12
Due date of the loan = September 10
Now,
The months in between March and September and the number of days in the particular months are
Month Number of days
April 30
May 31
June 30
July 31
August 31
------------------------------------------
Total number of days = 153
also,
Number of days left in March after 12 are (31 - 12 ) = 19 days
and,
Number of days in September before the due date = 10 days
Hence, the total time for loan = 19 + 153 + 10 = 182 days
since the included months does not have the month of February. Therefore,
the time for both leap year and non-leap year will remain same.
Answer:
Step-by-step explanation:
2x + 3.5x + 15 = -1.5
5.5x + 15 = -1.5
5.5x = -16.5
x = -3
y = 3.5(-3) + 15
= -10.5 + 15
= 4.5
(-3, 4.5)
