OK, a triangle first of all needs to have a certain condition satisfied. The length of one side of a triangle can not equal the length of 2 sides combined. So in a triangle a + b = c, a + b can not be less than c (a + b <span>≮ c</span>). Therefore, there are only a few possibilities that will work here. Let's find them:

16, 19, 43; no

16, 19, 50; no

16, 43, 50; yes

19, 43, 50; yes

Since only 2 out of 4 form triangles, there is a 50% chance you'll pick the right segments to form a triangle.

How do you solve 3x+7=x

vredina [299]

3x + 7 = x

First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like: $\frac{7}{-2}$ = x
Fourth, simplify $\frac{7}{-2}$ to $-\frac{7}{2}$ / Your problem should look like: $- \frac{7}{2}$ = x
Fifth, switch sides. / Your problem should look like: x = $-\frac{7}{2}$

Answer as fraction: $-\frac{7}{2}$
Answer as decimal: -3.5
