find teh value for y for which 2Xay =54?

Huh? \n\nIs this 2*x*a*y=54?\n\nOr 2*X*a^y=54 (which is what the text seems to imply).\n\nOr 2*Xa^y=54 such that Xa is "X subscript a" which would be a more logical question\n\nRegardless of the question, is it supposed to be solved in terms of the other variables? There is more than 1 variable but only one equation.

x*y=90\nx=2.5y\n\nSubstitute 2.5y in for x:\n(2.5y)*y=90\n2.5yy=90\n2.5/2.5 yy=90/2.5\nyy=36\ny^2=36\nSquareroot(y^2)=squareroot(36)\ny=36\n\nplug-in y:\nx*6=90\n(also known as 6x=90, as is normally written that way)\nx*6/6=90/6\nx=15\n\nThus, 6 and 15\n\ny=15

y varies kx\n30 = .... wait a minute this question is impossible to do lol, u need to know two sets of values ( y, x).. either you said the question wrongly or the person who made it is dumb

(6y^2-3y)(y+7)-->(2y)(y-1)(y+7)\nif that helps

Step 1: find y '\nStep 2: fill in x=1\nThat gives the right answer 2\n\nTh

I think the answer is x=1/2.\n\nIf x and y vary inversely, then xy = k, which is some fixed number. Taking the first two values, (3)(14)=k, so k=42.\n\nIf y=84, and k=42, then (84*x)=42, or x = 0.5

1. Move -36 to the other side by adding it.\n\n4y=2y+42+36\n\nnow the equation is...\n\n4y=2y+78\n\n2. Now move the 2y to the other side by subtracting it. This is called isolating the variable (y)\n\n4y-2y=78\n\nNow the equation looks like...\n\n2y=78\n\n3.Now divide both sides by 2 to get y by itself.\n\nYou finally get...\n\ny=39
