Answer:
Mark is 9 and his brother is 14.
The expression for Mark: 23 - 9 = 14
The expression for his brother: 23 - 14 = 9
Step-by-step explanation:
We know that 14 is 5 more than 9, and Mark is the younger one so he would be 9 and his brother 14. 9 + 14 also equals 23, so thats how you know you have the right answers.

Answer:
there is no x to solve, so there is no answer to that.
Let's recall that in a parallelogram:
1. The opposite sides are paralell
In our exercise. sides CZ and KG are paralell. And so do sides KC and GZ.
2. Those opposite sides are equal in length.
3. The opposites angles are equal. In our exercise, angle C and G are equal and so do angles K and Z.
4. That also mean that the angles at the top of the figure are supplementary. It means they add up to 180 degrees. We have the same situation with the two angles at the bottom of the parallelogram.
In our case then:

Now, we can find the measure of angles K and Z, as follows:
