Answer:

Step-by-step explanation:
We are given the following in the question:
"A temperature in kelvin is 273.15 greater than the temperature in degrees Celsius."
We have to write an equation that relates temperature K in Kelvin to temperature C in Celsius.
According to the given relation, we can write the equation:

is the required equation that provides a relation between temperature in Kelvin and temperature i Celsius.
Answer:
x=1, z=-2, y=3
Step-by-step explanation:
Substitution Method
Answer:
Step-by-step explanation:
The question will look like (3b)/(a^-2)
To simplify, note the (a^-2). It is a negative, so flip the placement of the monomial. Note that the term is located in the decimal, so when it is flipped, it goes to the numerator (vice versa if it is opposite)
(3b)/(a^-2) = (3b)(a²)
3a²b, or (A) is your answer choice
