Answer:
x=9
Step-by-step explanation:
3x + 25 = 2(4x – 10)
3x + 25 = 8x-20
3x-8x=-20-25
-5x=-45
5x=45
x=9
Answer:
300%
Step-by-step explanation:
$2.25 divided by $0.75 = 3 (new price divided by old price)
This means the price has gone up by 300% as $0.75= 100%
(I’m not sure I explained this very clearly, if you want me to rewrite it just say!)

Answer:
Perpendicular
Step-by-step explanation:
Parallel lines mean lines that have same slope but since both equations have different slopes which you can check by looking at m-value in y = mx + b. In this case m1 or first slope is -4/3 and m2 or second slope is 3/4.
Perpendicular means that both lines are reciprocal to each other. This means the perpendicular condition is or satisfies 
We have m1 = -4/3 and m2 = 3/4.
Therefore, -4/3 * 3/4 = -1 thus both lines are perpendicular to each other as it satisfies m1m2 = -1 condition.
