Answer:
Step-by-step explanation:
eq. of any line withslope 1/6 is
y=1/6x+c
∵ it passes through (-2,7)
so 7=1/6(-2)+c
c=7+1/3=22/3
eq. of line is
y=1/6x+22/3
Just divide the numbers by the starter and multiply it by the first one sorry if I’m wrong

Answer: $28.32</h3>
=========================================================
Work Shown:
18% = 18/100 = 0.18
18% of 24 = 0.18*24 = 4.32
The tip is $4.32
Adding this tip amount onto the original bill leads to 4.32+24 = 28.32
-------------
As a slight shortcut, we can use the multiplier 1.18 to get
1.18*24 = 28.32
This works because
1.18*24 = (1+0.18)*24 = 1*24 + 0.18*24 = 24 + 0.18*24
Notice the portion "24 + 0.18*24" can be found buried in the 1.18*24 expression. I applied the distributive property.
The multiplier 1.18 represents an increase of 18%
We can think of it as
100% + 18% = 1+0.18 = 1.18
Answer:
x = 5
Step-by-step explanation:
9x = 5x + 20
-5x -5x
4x = 20

4 4
4x/4 = x
20/4 = 5
x = 5
