Answer:
14.21 inches
Step-by-step explanation:
Given
1 inch = 14 feet
Required
Find the equivalent of 199 feet
Write out the given expression;
1 inch = 14 feet
Let x represent the equivalent of 199 feet in inches; Such that:
x = 199 feet
Write out both expressions
1 inch = 14 feet
x = 199 feet
Using cross multiplication; both expressions become
x * 14 feet = 199 feet * 1 inch
Divide both sides by 14 feet
![\frac{x * 14 feet}{14 feet} = \frac{199 feet * 1 inch}{14 feet}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20%2A%2014%20feet%7D%7B14%20feet%7D%20%3D%20%5Cfrac%7B199%20feet%20%2A%201%20inch%7D%7B14%20feet%7D)
![\frac{x * 14}{14} = \frac{199* 1 inch}{14}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20%2A%2014%7D%7B14%7D%20%3D%20%5Cfrac%7B199%2A%201%20inch%7D%7B14%7D)
![\frac{14x}{14} = \frac{199* 1 inch}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B14x%7D%7B14%7D%20%3D%20%5Cfrac%7B199%2A%201%20inch%7D%7B14%7D)

He has 24 meals that use milk in 8 days. If he finished 2 gallons in 24 sittings, he uses 2/24 of a gallon a day which simplifies to 1/12 gallon a day.
I got you fam
2(x - 4) - 4x = 0
2x - 8 - 4x = 0
-2x - 8 = 0
-2x -8 + 8 = 0 + 8 (add 8 both sides)
(divide both sides by -2)
x = -4
Hope this helps
