I know you can create an equation to solve this but its been a while since ive done this so im going to slowly write it out.
Day-1=12
2=18
3=24
4=30
5=36
6=42
7=48
8=54
9=60*
n=9
It's easier to work with problems such as –2.1x + 3.7 -5 + 4.9x when we rearrange the like terms vertically:
–2.1x + 3.7 -5 + 4.9x
becomes
–2.1x + 3.7
+4.9x -5

2.8x - 1.3 (answer)
Answer:

Step-by-step explanation:
The distance d between a point (m , n ) and a line in the form
Ax + By + C = 0 , is calculated as
d = 
Here (m, n ) = (6, 2 ) and
6x - y = - 3 ( add 3 to both sides )
6x - y + 3 = 0 → A = 6, B = - 1, C = 3
d =

Answer:
z=4
Step-by-step explanation:
1/4z-2/7=5/7
1/4z= 5/7+2/7
1/4z=1
z=4
