Answer: r = 9

Given:

16=10+\sqrt{3r+27}

Step-by-step explanation:

16-10=\sqrt{3r+27}

6=\sqrt{3r+27}

Taking square on bothsides, we get

36=3r+27

3r=36-27

r=\frac{9}{3}

r=3

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

                  = 10 + √36 = 16
