What is 2x divided by 3 equals x divided by 2 plus 20?
2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
Y varies directly as the square of r If y equals 80 when are equals 4 find y when are equals 6?
80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120
4x - 7 equals 5x - 2 what does x equals?
4x-7=5x-2 x=-5
How do you factor 16x squared?
4x times 4x equals 16x2.
What is 4x plus -12 equals 8?
If: 4x+(-12) = 8 then 4x = 20 and x = 5
What is 120- equals?
If 4x=120, x=30.
What is 4x-7 equals x plus 59?
120
What is 2x divided by 3 equals x divided by 2 plus 20?
2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
What is 4x -17 equals 3?
4x -17 equals 3 4x equals 20 x equals 5
Y varies directly as the square of r If y equals 80 when are equals 4 find y when are equals 6?
80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120

4x-14
What could be the equation of a line parallel to the line y equals 4x?
y equals 4x+1 is a parallel line to y equals 4x.
How do you do 2x plus y equals -12 -4x-2y equals 30?
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.
4x plus 5y equals 51 4x - 5y equals 21?
Simultaneous Equations. 4x + 5y = 51 4x - 5y = 21 eliminate 'y' by addition. Hence 8x = 72 x = 72/8 x = 9 When x = 9 Substitute into eith equation. 4(9) + 5y = 51 36 + 5y = 51 5y = 51 - 36 5y = 15 y = 3 Hence the answer is ( x,y) = ( 9,3).
