Can 0 be divided into anything? (answer)

Another way to see why this is true:  try dividing by a very small number.  For example:  2/0.001 = 2000.  Now make that denominator even smaller:  2/0.0001 = 20,000.  And smaller:  2/0.0000001 = 20,000,000. As you can probably tell by now, as the denominator...

HOW MANY CUPS OF SLICED CARROTS MAKES A POUND? (answer)

Also, to find out how many pounds = 128 grams, you can set up a ratio: 1 pound : 453.6 grams :: x pound : 128 grams.  Same as 1/453.6 = x/128 Multiply both sides by 128:  128/453.6 = x Do the division:  x = 0.282 pounds, or just over 1/4 of a pound, or just over 4 ounces...

what is 9 + 2x = x + 96 (answer)

Get everything with x on the same side:  9 + 2x - x = x - x + 96  (subtract x from both sides) Simplify/combine:  9 + x = 96 Isolate x on one side:  x = 96 - 9  (subtract 9 from both sides) Solve:  x = 87

x + y =3 and x = 1/2y (answer)

x = 1/2 y = y/2;   y/2+y = 3;   1.5y = 3;  y = 2 x + 2 = 3; x = 3-2 = 1 Or x+y = 3 or x = 3-y;  (3-y) = 1/2 y = y/2;  3 = y/2 + y = 1.5y;  y = 2 x+2 = 3; x = 1

Solve for Line JL (answer)

If you solve for x by using 4x-3 = 3x+2 then x=5, and each of the lines HI and JI is 17.  But without at least one more measurement (angle or side), I don't think there is any way to solve for any other side, including HL or JL.  Anything to add?

graphing functions (answer)

Sorry... we cannot answer as written.  What do the [[ ]] around x mean?  Absolute value of x, as in |x|?  Is [[x]]+2/2 actually (x+2)/2?  Is x < 6, or x < 0?   Help!

How to write proportions based on a triangle's side lengths? (answer)

OK, so you have an Isosoles triangle (2 equal sides), and maybe even an equilateral triangle (all 3 sides equal,), but we don't know that.  Question:  is the "one side" that is 28 also one of the x-sides?  Or the 3rd side?  And units of measurement don't really matter...

How to combine the given terms in simplest form? (answer)

(-xy)3 = -x3y3, and does NOT = -xy3, since each term inside the ( ) must be cubed. An exponent raised to another exponent is multiplied by that other exponent, so (y3)4 = y3x4 = y12.   The exponents of the same terms are simply added:  (x)(x4) = x5.    ...
