If y equals 3x and 3x equals 12 then what does y equals?
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
In math x and y equals what?
In math x and y means unknown answer. The mystery numbers are always different like x doesn't mean 3 and y doesn't mean 0.
72 plus y equals 180 find the value of y?
Well, honey, if 72 plus y equals 180, then y must be 108. Simple math, darling. Now go out there and conquer the world with your newfound knowledge.
What is 2y when y equals 8?
Oh, dude, you're hitting me with some math here! Okay, so if y equals 8, then 2y would be 2 times 8, which equals 16. It's like, you know, basic multiplication and stuff. So yeah, 2y is 16 when y equals 8.
If x squared y squared equals 25 xy equals 5 prove that x over y plus y over x equals 5 somebody HELP?
x/y = 5/(y^2) and y/x = 5/(x^2). So x/y + y/x = 5/(y^2) + 5/(x^2), which equals 5x^2/(x^2 y^2) + 5y^2/(x^2 y^2) equals 5(x^2 + y^2)/25 equals (x^2 + y^2)/5. x^2 = 25/y^2, so you get (25/y^2 + y^4/y^2)/5 equals ((25 + y^4)/y^2)/25, which shows that your math teacher is on crack. Seriously, I'm not sure that's true.
