There are x boys playing in the park. the number of girls playing in the park is equal to the square root of the number of boys. if the total number of boys and girls playing in the park is 42, find the number of boys.

Let us set up the equation using the given information

Boys = x
Girls = √x
Boys + girls = 42

Equation: x + √x = 42

You can now work out this equation to solve for x, OR reason your way through it. By substituting numbers into the equation. Try 36
               36 + √36 = 42
               36 + 6     = 42
                         42 = 42

ANSWER: 36 Boys (and 6 girls)

Hope this helps! God bless!! :)
