Sara owns a tree farm. Variety A of a pine tree is shipped to her at 12 inches tall and grows at a rate of 14 inches per year. Variety B of a pine tree is shipped to her at 2 inches tall and grows at a rate of 16 inches per year. Which equation can be used to determine the number of years, x, at which the trees will be an equal height?

14 + 12x = 16 + 2x
14 + 12, x, = 16 + 2, x

16 + 12x = 14 + 2x
16 + 12, x, = 14 + 2, x

12 + 16x = 2 + 14x
12 + 16, x, = 2 + 14, x

12 + 14x = 2 + 16x
12 + 14, x, = 2 + 16, x

The equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true? a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of 5/9 degree celsius. a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit. a temperature increase of 5/9 degree fahrenheit is equivalent to a temperature increase of 1 degree celsius. a) i only b) ii only c) iii only d) i and ii only
