Answer 1

Answer:

The trees will be the same size in 12 years

Step-by-step explanation:

given the 3-foot tree can grow 1.5 feet per year

given the seeds can grow 1.75 feet per year

The trees will be the same size but it will take a while To find out how long that take we set up an equation to be

3 + 1.5x = 1.75x

3 = 0.25x

x = 12

x represents for years it take

Answer 2

Answer:

After 12 years both will be in same height

Step-by-step explanation:

Let 'x' be the number of years .

After 'x' years both will be in same height

Genevieve:

Rate of growth per year = 1.5 ft

Rate of growth after 'x' years = 1.5 * x = 1.5x

Height of tree after 'x' years = 3 + 1.5x

Marcus:

Rate of growth per year =1.75 ft

Rate of growth after 'x' years = 1.75 * x = 1.75x

Height of tree after 'x' years = 1.75x

After 'x' years both will be in same height

1.75x = 3 + 1.5x

1.75x - 1.5x = 3

         0.25x = 3

                x = $\frac{3}{0.25}$

                $x =\frac{3*100}{0.25*100}=\frac{300}{25}$

x = 12
