Solve for Y:<br> 2/3 (y+57 )= 178

sattari [20]

Y= 210 you have to distribute 2/3 to y then to 57 and your equation would be 2/3y + 38= 178 then you take 38 and subtract 178 - 38 and you get 140 then you divide 140/ (2/3) and you will get 210 as your answer.(:

Simplify: √27 A. 3√3 B. 9√3 C. 3√9 D. 5√3

blagie [28]

To simplify square root 27, find two numbers that equal 27. But also, one of the numbers should be a perfect square (such as 4, 9, 36...).

9*3=27. The square root of 9 is 3, which makes it a perfect square. So, the answer is A.
