Write two equations to model the growth of each tree, and set the equal to each other.

Let x equal the years.

For Type A, the equation is 3x+48 because the tree grows at 3 inches per year and, it started at 4 feet (48 in).

For Type B, the equation is x+72 because the tree grows at 1 inch per year, and it started at 6 feet (72 in).

3x+48=x+72

*Isolate the variable by subtracting x from each side*

2x+48=72

*Subtract 48 from both sides*

2x=24

*Divide both sides by 2*

x=12 years

Hope this helps!!

3x+3 =30

Step-by-step explanation:

Let x be the smallest integer

x+1 be the next smallest

x+2 be the third

x+ x+1 + x+2 = 30

Solve x - 3 1/8 = 5/12

Anna007 [38]

Answer:

$\large\boxed{x=\dfrac{85}{24}=3\dfrac{13}{24}}$

Step-by-step explanation:

Convert the mixed number to the fraction:

$3\dfrac{1}{8}=\dfrac{3\cdot8+1}{8}=\dfrac{25}{8}$

METHOD 1:

$x-3\dfrac{1}{8}=\dfrac{5}{12}\\\\x-\dfrac{25}{8}=\dfrac{5}{12}\\\\\text{the common denominator is 24}\\\\x-\dfrac{25}{8}=\dfrac{5}{12}\qquad\text{multiply both sides by 24}\\\\24x-(3)(25)=(2)(5)\\\\24x-75=10\qquad\text{add 75 to both sides}\\\\24x=85\qquad\text{divide both sides by 24}\\\\\boxed{x=\dfrac{85}{24}}$

METHOD 2:

$x-3\dfrac{1}{8}=\dfrac{5}{12}\qquad\text{add}\ 3\dfrac{1}{8}\ \text{to oboth sides}\\\\x=\dfrac{5}{12}+3\dfrac{1}{8}\\\\x=\dfrac{5\cdot2}{12\cdot2}+3\dfrac{1\cdot3}{8\cdot3}\\\\x=\dfrac{10}{24}+3\dfrac{3}{24}\\\\x=3\dfrac{10+3}{24}\\\\\boxed{x=3\dfrac{13}{24}}$
