Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.

Infinite solution Bc both sides are equal
Answer:
z = 5/2y -1
Step-by-step explanation:
We observe that z has ...
- 1 added
- the sum multiplied by 2/5
To solve for z, we undo these operations in reverse order.
![\dfrac{2}{5}(z+1)=y\qquad\text{given}\\\\z+1=\dfrac{5}{2}y\qquad\text{multiply by 5/2}\\\\\boxed{z=\dfrac{5}{2}y-1}\qquad\text{subtract 1}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%28z%2B1%29%3Dy%5Cqquad%5Ctext%7Bgiven%7D%5C%5C%5C%5Cz%2B1%3D%5Cdfrac%7B5%7D%7B2%7Dy%5Cqquad%5Ctext%7Bmultiply%20by%205%2F2%7D%5C%5C%5C%5C%5Cboxed%7Bz%3D%5Cdfrac%7B5%7D%7B2%7Dy-1%7D%5Cqquad%5Ctext%7Bsubtract%201%7D)
The sequence 2, 3, 5, 7, 11 are the first five prime numbers. A prime number is a positive integer which has exactly 2 positive integer factore, one factor being 1 and the other factor is the positive number itself. So the next prime numbers after 11 are 13, then 17, 19, 23, 29, 31, 37, 41, 43
