Line YZ is the midsegment of triangle QRS because it connects the midpoints of lines QR and RS. We would solve for x by appying the midsegment theorem which states that the midsegment is half the length of the third side or base. This means that

YZ = 1/2(QS)

x + 2 = 1/2 * (3x - 8)

2(x + 2) = 3x - 8

By opening the parenthesis, we have

2x + 4 = 3x - 8

Collecting like terms, we have

3x - 2x = 4 + 8

x = 12

Option C is correct

A bag contains purple marbles and white marbles, 68 in total. The number of purple marbles is 4 less than 5 times the number of
galina1969 [7]

Answer: 56 purple marbles.

Step-by-step explanation:

Let be "p" the number of purple marbles in the bag and "w" the number of white marbles in the bag.

You can set up the following System of equations:

\left \{ {{p+w=68} \atop {p=5w-4}} \right.

You can use the Substitution method to solve the System of equations. The steps are shown below:

1. You need to substitute the second equation into the first equation:

(5w-4)+w=68

2. Now you must solve for "w":

5w-4+w=68\\\\6w-4=68\\\\6w=68+4\\\\6w=72\\\\w=\frac{72}{6}\\\\w=12

3. Substitute the value of "w" into second original equation and then evaluate in order to find the value "p":

p=5(12)-4\\\\p=60-4\\\\p=56
