Answer:
2 lessons per day for 27 days and 3 lessons a day for 4 days.
Step-by-step explanation:
66/31 = 2 4/31
Since 66 divided by 31 is 2 with remainder 4, you need to do 31 days of 2 lessons per day. To do the extra 4 lessons, do one more lesson per day for 4 of those days.
That results in:
2 lessons per day for 27 days and 3 lessons a day for 4 days.
Check:
2 lessons a day for 27 days = 2 * 27 = 54
3 lessons a day for 4 days = 3 * 4 = 12
54 + 12 = 66
If you do 2 lessons a day for 27 days and 3 lessons a day for 4 days, you will do the 66 lessons.
Y - (-5) = -7
---------------------------
Simplify
y + 5 = -7
-------------------------------------
Subtract 5 from each side
y + 5 - 5 = -7 - 5
y = -12
--------------------------------------------
y = -12 is your answer
Answer:
E. 1,700 is your answer.
Step-by-step explanation:
What you do is you add 668 + 575 + 453 together.
668 + 575 + 453 = 1,696.
The hundreds place is the 9. Since the 9 is bigger than 4 it gets rounded up. That means the 6 in front of the 9 becomes a 7 and 9 and 6 become a zero.
E. 1,700 is your answer.
I believe it would be y=-1/3x-2
C is correct answer, passes through (5,-1) and also has slope of 3/4
