Answer:
5, -12, -3
Step-by-step explanation:
A constant is a number by itself. Here, you can see that 5X is paired with a letter, that means that 5X is not a constant. So you could say that any whole number is a constant number and in this problem, 5, -12 and -3 are all the constant numbers in this expression.
No. If 4x= 24 then x=6. 7 multiplied by 6 equals 42, not 35 so this is not a ratio.
