1. C
2. 3, because I used a proportion table
Answer:
least common denominator for 2 and 5 is 10.
Answer:
No
Step-by-step explanation:
Direct variation: two variables, one variable is a constant multiple of another variable
y = k x .... k constant
-x+4y=-2
4y = x - 2
y = 1/4 x -1/2 ..... y = k x + b y is not a simple multiple of x
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
