Answer:
Infinite number of solutions.
Step-by-step explanation:
Are the equations written correctly? They are identical. Since they overlap, every point is a solution for as long as the lines reach. Since no one is stopping them, the answers are infinite.

Answer:
X=18, Y=6
Step by Step Explanation:
This is a little long winded.. Let's solve for Y first.
First looking at the problem, you can note a few things. First of all, there is an Isosceles triangle, and there is an equilateral triangle. Where they connect, there is a 90° angle.
Now, all equilateral triangles have the same angle measurement. 60°. Now, if you look where the right angle is, it is showing a 60° angle, a total of 90°, and an unknown area. So simply subtract. 90-60=30. Divide that by 5, and you have your answer of 6.
Now let's solve X. X is very simple. On an isosceles triangle, the two top sides are the same length. And one of the top sides is the same size as the equilateral triangle. And on equilateral triangles, all sides are the same.
So the 11 transfers over to the X side. So let's make a small equation. 11=X-7. To make it even, let's add 7 to both sides. 11+7=X+7-7. Simplify to get 18=X, which is your answer.

Good luck! I’d appreciate if you made this the brainliest answer! :)
Answer:
24.44 percent
Step-by-step explanation:
F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
