Answer:
The greatest number of bracelets she can buy is 63.
Step-by-step explanation:
12 + 0.60x ≤ 50
- Since we already have the inequality, we have to start picking random numbers(until there are no more solutions):
1.) 12 + 0.60(63) ≤ 50
12 + 37.8 ≤ 50
49.8 ≤ 50
Since 49.8 ≤ 50 is always true, there are infinitely many solutions.
- Now we know that she can buy 63 bracelets, we have to figure out if she can buy more:
2.) 12 + 0.60(64) ≤ 50
12 + 38.4 ≤ 50
50.4 ≤ 50
Since 50.4 ≤ 50 is false, there is no solution.

Answer:
Step-by-step explanation:
The sum of the angles on a straight line is 180 degrees. Therefore,
Angle XYZ + angle MYZ = 180
Angle XYZ + 115 = 180
Angle XYZ = 180 - 115 = 65 degrees
The sum of the angles in a triangle is 180 degrees. It means that
Angle XZY + angle YXZ + angle MYZ = 180
Therefore,
4k + 5 + 6k + 10 + 65 = 180
4k + 6k + 5 + 10 + 65 = 180
10k + 80 = 180
10k = 180 - 80 = 100
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10k/10 = 100/10
k = 10
