Answer:

3 * 18= 54 and 54/18 = 3

Step-by-step explanation:

Given

Sections = 3

Measurement=18 per section

Total\ Measurement=54

Required

Model the scenario

The model of this scenario is:

Sections * Measurement = Total\ Measurements

This gives:

<em />3 * 18 = 54<em> -- This represents the multiplication model</em>

Divide both sides by 18

3 * 18/18 = 54/18

3 * 1 = 54/18

3 = 54/18

Reorder

<em />54/18 = 3<em> -- This represents the division model</em>

sdas [7]

Answer:

10 + (\frac{2}{3}) a = 50 is the CORRECT equation.

Step-by-step explanation:

The given question is INCOMPLETE.

Javier asks his mother how old a tree in their yard is. His mother says, “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.” Javier writes the equation { 10 + 2/3} where a is the tree’s age in years. His equation is not correct. What error did he make?

Now here:

a:  The tree’s age in years.

Also,  “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.”

⇒ 10 +  two-thirds of that tree’s age  = 50

\implies 10 + (\frac{2}{3}) a = 50

But in the equation written by Javier, the the third fraction is NOT MULTIPLIED by the age of the tree a in Years.

So, the written equation by Javier is Incorrect.

Now, solving the written correct equation for the value of a, we get:

\implies 10 + (\frac{2}{3}) a = 50\\\implies  (\frac{2}{3}) a = 40\\\implies a = 40 \times  (\frac{3}{2})  = 60\\\implies a  = 60

Hence the correct  age of the tree = 60 years
