18-3=15
Originally pay 25 = 75
450-75=375
375 + 75 = 450
C) 18 people were originally going on the trip and 15 are going now.
Idk about D
Answer:
(Neither they aren't parallel because they intersect and they aren't perpendicular because while they intersect they don't make a 90 degree angle and the point of intersection is (1.5,0) and (0,2) since it intersects at 2 places.) -Raymond :3

Answer:
Triangle 3
Step-by-step explanation:
A 3:4:5 triangle or any triangle of the same ratio (Like 6:8:10) is always a right triangle
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
<span>12*(4x−5)/52=10 if this is the equation
the value for x would be
x </span>≈ 12
