Question

The length of RT is 4x-4. Given that point S is between pont R and T , where the length of RS is 2x+6 and the length of ST is 16, what is the length of RS?

Answer 1

RS = 32

Explanation:

Since RS and ST are two parts of the same line, we can say that RS + ST = RT

Now we plug in the numbers:

RS = 2x+6

ST = 16

RT = 4x-4

2x+6 + 16 = 4x-4

2x+22 = 4x-4

26 = 2x

13 = x

RS = 2x+6 --> 2(13) +6 --> 26+6 --> 32
