Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.

Answer: -2,3,&4
Step-by-step explanation:
Correct on edgenuity
'of' means muiptly
4/5 of a pizza
'a pizza' means 1 whole pizza
4/5 of 1=4/5
eats 2/3 of that share (meaning 4/5)
2/3 of 4/5=2/3 times 4/5=8/15
so she ate 8/15 of pizza
