Answer:

Step-by-step explanation:
(This can be simplified, because when you divide expressions with exponents that have the same bases, you can subtract the exponents from the one with the corresponding base)

=

Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:
с 1 and 3
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the functions and constants are given as follows:
- 3. 8y = 6x -> k = 6/8 = 3/4.
Equations 1 and 3 have the same constants, hence option c is correct.

The answer is C. 75.
Explanation: Let’s go from smallest to largest.
A, 25, would not work because you can’t multiply 15 by a whole number to get 25.
B, 50, doesn’t work because again, you can’t multiply 15 with a whole number to get 50.
C, 75, is the CORRECT ANSWER because 5x15 is 75, 25x3 is 75, and 15x5 is 75. Each number can be multiplied by a whole number to get 75.
Answer:
The answer is Arithmetic Sequence.
