Y+3=-36
-3 -3
So Y equals -39
Well.... first lets break this problem up. and work on the left side first
soo we solve this ↓
14/21.2 = 0.66
now lets plug in our values. The left side will just be replaced by 0.66
Soooo
0.66 = n/15
so this means we do the opposite on both sides of what n and 15 are doing
In this case they are dividing so yes we are doing the opposite by multiply.
sooooo
0.66 = n/15
×15 = x 15 they cancel out on the right hand side and lets solver for the left side.
0.66 x 15 = 9.9
so that means
n = 9.9
or we could round it and just say 10
n = 10
hope this helps:P
2x - 3 [5x - 2(6-x)] =
2x - 3 [ 5x - 12 + 2x ] =
2x - 3 [ 7x - 12 ] =
2x - 21x + 36 =
-19x + 36
The median is their average (60+99)/2=79.5
If there were any odd number of numbers it would be the middle number. When there is an even number of numbers, the median is the average of the two middle ones.
The coordinates of B are (-2 , 9)
Step-by-step explanation:
A (8, 4)
M (3 , -1)
To calculate a midpoint you have to add the corresponding coordinates of each point and divide them by 2
(Ax + Bx) / 2 = Mx
(8 + Bx) / 2 = 3
8 + Bx = 3 * 2
Bx = 6 - 8
Bx = -2
(Ay + By) / 2 = My
( -1 + By) / 2 = 4
-1 + By = 4 * 2
By = 8 + 1
By = 9
The coordinates of B are (-2 , 9)
