12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...
BTW THIS WAY IS A LOT EASIER.
12/30 = 2/5
18/45 = 2/5
So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)
Multiplication equation can be -2x where x represents number of day.
Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.
According to the question,
The money borrowed is $2 each day
multiplication equation can be written as the product of 2 and -x variable which will represent the number of days and - will represent the borrowed money. so the multiplication equation can be -2x where x represents number of day.
Therefore, multiplication equation can be 2*(-x) where x represents number of day.
