Answer:
-1 17/18
Step-by-step explanation:
I solved this.
Andy to get to Willie's house = 15 ways
Andy to get to Willie's house = 45 ways
<h3>
How to determine the ways</h3>
From the information given, we have that from
Andy's house to Billy's hometown = 3 roads
Billy's hometown to Willies house = 5 ways
To travel from Andy's house to Willies house, we should multiply the number of ways
= 3 × 5
= 15 ways
Dan's ranch to Andy's house = 1 road
To Willie's house = 2 roads
For Andy to get to Willie's house, we have;
= 3 × 15
= 45 ways

Answer:
4/9
Step-by-step explanation:
8/2=4
18/2= 9
Let z = sin(x). This means z^2 = (sin(x))^2 = sin^2(x). This allows us to go from the equation you're given to this equation: 7z^2 - 14z + 2 = -5
That turns into 7z^2 - 14z + 7 = 0 after adding 5 to both sides. Use the quadratic formula to solve for z. The only solution is z = 1 (see attached image). Since we made z = sin(x), this means sin(x) = 1. All solutions to this equation will be in the form x = (pi/2) + 2pi*n, which is the radian form of the solution set. If you need the degree form, then it would be x = 90 + 360*n
The 2pi*n (or 360*n) part ensures we get every angle coterminal to pi/2 radians (90 degrees), which captures the entire solution set.
Note: The variable n can be any integer.
