in -x+y=4
x = y−4 y = x+4
Answer:
The next number in the sequence is 36.
Step-by-step explanation:
Consider the provided sequence.
4, 9, 16, 25
The number 4 can be written as 2².
The number 9 can be written as 3².
The number 16 can be written as 4².
The number 25 can be written as 5².
The general term of the sequence is: 
Thus, the next term will be:



Therefore, the next number in the sequence is 36.
X=4 because you add 19 to both sides which gives u -44 and -11 x 4 = -44
Answer:
27 miles
Step-by-step explanation:
Find the rate or speed that Shawn hikes at. Find this reduced to lowest terms.
speed = distance / time
speed = 12 miles / 4h
speed = 3miles / h
Every hour, Shawn hikes 3 miles.
Multiply speed by time to find distance.
3mph X 9h = 27 miles
Therefore Shawn could hikes 27 miles in 9 hours.
