Here is how you would set it up...

You would to 12/100 = x/2 and cross multiply and solve by division. I believe. I'm almost positive that's how you do it. If that don't work out, comment and I'll respond.

Can someone explain how to do this
alex41 [277]

When any angle bisects with other angle then both the angles are equal.

Then, m of angle ABD = angle CBD

ABD = 70

ABD = CBD = 70°

ABC = 70 + 70 = 140°

Find a value for x if 1/x > x
Ymorist [56]

Since x can't be zero (it sits at the denominator of the left hand side), let's split cases:

If x is positive

It this case, we can multiply both sides by x without changing the inequality sign:

\dfrac{1}{x} > x \iff 1 > x^2 \iff x \in (-1,1)

But since we're assuming that x is positive, we can only accept the numbers between 0 and 1.

If x is negative

It this case, in order to multiply both sides by x we have to change the inequality sign:

\dfrac{1}{x} > x \iff 1 < x^2 \iff x \in (-\infty,-1) \cup (1,\infty)

But since we're assuming that x is negative, we can only accept the numbers which are smaller than -1.

So, putting all the pieces together, we have that the solution is given by the following interval:

(-\infty, -1) \cup (0,1)

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in t
Svetllana [295]

Answer is when a is negative

To solve inequalities, you are trying to get the X variable by itself with a positive charge of 1. If the coefficient in front of it is negative, you must flip the sign in the other direction.

Example:

-3x < 9

divide each side by a negative 3. This means we have to flip the sign.

x > -3
