Distance = rate * time
580 = (80+65) * t
T = 4 hours
First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.
Xy=k, whenever the product of two variables is a constant it is called inverse variation. This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.
It is easy to spot as xy=k or y=k/x.
Answer:
The density of the material must be at least 1.5 g/cm³.
Step-by-step explanation:
The answer is 5x^2y. The lowest exponent would be the GCF for each term if it has one
