R=12 because in order to get rid of the 2 in the denominator you have to multiply both sides by 2. Then the equation reads 9r-18<90. Next add the 18 to her 9r<108. And lastly divide by 9 to solve for r. Which in this case is 12

What times itself equals 32 (sorry i suck at maths)
julia-pushkina [17]
You're asking for the square root of 32. you can actually do this on a calculator really easily. just type in the number (in this case, 32) and press the square root symbol (looks like a calculator). the square root of 32 is a long string of decimals,  but it's approximately 5.7 :) good luck
