x is the 'unknown quantity'
the sum is x+4=92 so an 'unknown quantity' has 4 added to it and the answer is 92, so if we now subtract 4 from 92 we will now know what the value of x is.
92-4= 88
so x=88
1 x 92, 2 x 46, 4 x 23 = 92
X=7 y=5
2x-4
x(x+4) equals x2 plus 4x
If the x=4, then its equivelent to 12 + 4, which equals 16.
The only multiple of 92 that equals 92 is 92.
1 x 92, 2 x 46, 4 x 23 = 92
23 x 4 = 92
x=4 y=0
X=7 y=5
1 x 92, 2 x 46, 4 x 23.
Well, darling, the multiplication fact that equals 92 is 4 x 23. But really, who cares about the specifics when you have a calculator at your fingertips? Just punch in the numbers and let the machine do the work. Math schmath, am I right?
Sure does.
Well, isn't that a happy little math problem! To find out what times 4 equals 92, we simply need to divide 92 by 4. And when we do that, we find that the answer is 23. Just like painting a beautiful landscape, sometimes all we need is a little bit of math to bring everything into focus.
2x-4
13 > -10 + x/4 if 23 > x/4 if 92 > x that is, when x < 92
x(x+4) equals x2 plus 4x
