Question

Solve the following three equations

Answer 1

2 sq rt 33

Explanation:

1st step: subtract one, each side

(radical 2/3)r = 22

2nd step: set up a proportion

(radical 2/3)r = 22

3rd step: cross-multiply

radical 2*r = 66

4th step: solve for 'r'

r = 66 / radical 2

5th step: rationalize the denominator

multiply numerator and denominator by radical 2

6th step: simplify

(66
`√(2)`) / 2 = 33
`√(2)`
