Answer:
7.5 or 15/2
Step-by-step explanation:
x-3x+6=2x-24 -- Combine like terms
-2x+6=2x-24 -- Add 2x to each side
6 = 4x-24 -- add 24 to each side
30 = 4x -- divide by 4
15/2 or 7.5 = x

Answer:
y = 6.22
You can solve this in two ways.
1.) Use SOH CAH TOA:
I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.
2.) Use Law of Sines:
Solve for the last angle inside the triangle first.
Then use the angle you found (40°) in the equation.
B is the correct answer because 1 gallon of gas is 1.05 dollars, so 15 × 1.05 is 15.75...
