Answer:
12
Step-by-step explanation:
if you divide 156 students into 13 cabins you divide it into equal groups, once you divide all of it to equal groups you get 12 students in each cabin.
Answer:
(6, -9)
Step-by-step explanation:
Our system of linear equations is:
6x + 2y = 18
-4x - 2y = -6
When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:
6x + 2y = 18
+ -4x - 2y = -6
____________
2x + 0y = 12
x = 12/2 = 6
Plug this back into one of the original equations to find y:
-4x - 2y = -6
-4 * 6 - 2y = -6
-24 - 2y = -6
-2y = 18
y = -9
The solution is (6, -9).
Answer:
it would be 8 to 3
which is not equivalent
Step-by-step explanation:
the reason why is because of this
3, 6, 9, 12.
not:
3, 6, <em>8, </em>12.
18%, because 50 - 100, meaning 1 is 2% so 9x2 is 18
Answer:
See explanation
Step-by-step explanation:
There are three possible cases:
1. Point N lies between M and P, then MN + NP = MP. Consider needed difference:
2. Point N lies to the right from point P, then MP + PN = MN. Consider needed difference:
3. Point N lies to the left from point M, then NM + MP = NP. Consider needed difference:
