If you can only use 3 of these numbers once to find a sum of 30 without subtracting or adding additional numbers, what three numbers would you use out of 1, 3, 5, 7, 9, 11, 13, and 15? ()+()+()=30
Answers
Answer:
The correct answer is
It is impossible to add odd numbers (1, 3, 5, 7, 9, 11, 13, and 15) and odd number of times (3) to get an even number (30)
Step-by-step explanation:
1, 3, 5, 7, 9, 11, 13, and 15 are all odd numbers and 30 is an even number
When odd numbers are added even times the answer is always even for example 3 + 5 = 8, and when odd numbers are added odd times the answer is always odd for example 1 + 5 + 7 = 13
It is not possible to add three odd numbers to get an even number
Where x = odd therefore x + 1 = even = y say
hence 2 × x = 2×(y-1) = 2·y - 2 = even number
Also 3 × x = (3y -3) = odd number
Answer: The answer is 7+(3+5)+15 = 30

4 hours and 25 minutes before 2:95 am would be 9:40pm
Answer:10:20 pm
Step-by-step explanation:
Time is seperated into 2 sets of 12 hours, am and pm; and 24 hours with each being 60 minutes. AM is morning and PM is afternoon.
The question is what time is 4 hours and 25 minutes before 2:05 in the afternoon. This means you subtract.
205 - 425= -220
Then, because it is negative, you change it from am to pm and subtract 220 from 1200=
1200-220=980
9:80 is has too high a number in the minutes section (the second part) so you see how many sets of 60 are in 80. There is one set of 60 meaning there is one hour added to the hour side (the left side):
9+1: 80-60
10:20
10:20 pm is the final answer.

Now, assuming that for 10 years, it is not being paid.
Let's calculate for the money that is now owed.
=> 2000 dollars * . 09 = 180 dollars for 1 years
=> 180 dollars * 10 years = 1800 dollars
=> 2000 + 1800 = 3800 dollars for 10 years.

Use point-slope form with the perpendicular slope and the point (-3, 1):
You can simplify this if you want to (maybe to make it look a bit more "cleaner") and either put it as standard form or slope-intercept form.

You just divide each by one of there common factors (except from 1 and 0)
Eg.10÷2=5
12÷2=6
10/12
Next look for a common divisor that works for both the top (numerator) and bottom (denominator) numbers. Incidentally, think 'Notre Dame' or ND if you cannot remember which is which.
Dividing by 2 works for both numbers, so dividing the '10' and the '12' by 2 gives you a simplified form of 5/6.
And voila! That's your answer!
