Answer:
a. are for the same time period
Answer:
Step-by-step explanation:
It must end in 
(divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is 
.
We want to make 
as low as possible because it's a higher digit than 
.
If is as low as possible, we have that the sum is 
. Uh-oh. has to be even! So 
doesn't work.
If 
, we have that the sum is 
. Yay!
So, the answer is 
When we are looking for the mid point, we are looking for a point that is an equal distance from point R and S.
Since the x value has no change, we can ignore it.
For the y value, we want to simply find the difference between the points (7 - 1 = 6) and then divide that value by 2 (6 / 2 = 3).
You can then subtract that value from the higher Y value, where you will get 4.
Leaving you with the coordinate (3,4)
Hope this helped. There are definitely more ways you could find to solve this, but this works best for this problem.
Answer:
28
Step-by-step explanation:
Plug in 2 for x and 3 for y.
6(2) + 7(3) - 5 =
12 + 21 - 5 =
33 - 5 =
28
