The second one, because the price of the candle is $4, meaning the equation would have to be 4x+3=19
Consider, pls, this option:
1. if a required line has a form y=ax+b, then points A(-1;6); B(6;k) and C(20;3) belong to it.
2. According to the item 1 it is possible to make up the system of equations for A and C:

Knowing, that a=-1/7 and b=41/7, it is possible to write the equation of required line:

3. Using coordinates of point B:

Answer: 5.
Answer: 11
Step-by-step explanation:
If 15 workers can paint 18 houses in 24 days, how many days will 40 workers take to paint 22 houses?
--------------
# of days are inversely related to # of workers and directly related
to # of houses.
--------------
d = kh/w
---
Solve for "k" using "15 workers can paint 18 houses in 24 days"
24 = k*18/15
k = 15*24/18 = 15*(4/3) = 20
--------------
Equation:
d = 20h/w
---
Solve: How many days will 40 workers take to paint 22 houses?
d = 20*22/40
d = 11 days
I don't think a decimal number could have 2 decimal points.
