What is the value of x in the equation 5x plus 3 -7 divided by 2 equals 56?
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
Two numbers that when added equal 56 and when multiplied equal 783?
X + Y = 56 [therefore] X = 56 - Y XY = 783 [therefore] (56 - Y)(Y) = 783 56Y - Y^2 = 783 solve for Y, then don't forget to plug Y back into the original and find "X" (X = 56 - Y ) a+b = 56 AND: ab = 783 substitution: a = 56-b (from addition equation) put this back into the multiplication equation: (56-b)b = 783 expansion: 56b -b^2 = 783 rearrange: -b^2 + 56b - 783 quadratic formula: b = (-56+sqrt(3136-4(-1)(-783))) / -2 and b = (-56-sqrt(3136-4(-1)(-783))) / -2 b=27 and b=29 from the addition equation: 56-27 = a=29 56-29 = a =27 it's kind of a "repeat" question
What is the center of a circle for the equation 3x2 plus 3y2 - 30x plus 27 equals 0?
56
To solve 7x equals 56 you must do what to both sides?
7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
Which values of x are soluteto the equation below 15x2-56 equal 88 plus 6x2?
If: 15x2-56 = 88+6x2 Then: 9x2 = 144 And: x2 = 16 So: x = 4
