If it took 4 miles per hour you multiply that twice cuss its traveling back then forth so you repeat the same process 30 miles times 2 which is 60 hope this helps.
60 is the base OK. I think am right
Where are the choices- lololol
Answer:
y = (1/2)x - (15/2)
Step-by-step explanation:
goal: to rearrange the expression such that it is in the form
y = f(x); where f(x) is an expression in terms of x
given:
x - 2y = 15 (subtract x from both sides)
-2y = 15 - x (multiply both sides by -1 to make left side positive)
2y = -15 + x (divide both sides by 2 and rearrange)
y = (1/2)x - (15/2)
Let's see if we can find a pattern:
Row number 1 has 
seats
Row number 2 has 
seats
Row number 3 has 
seats
Row number 4 has 
seats
Can you see the pattern? After 
rows, we have added 
seats.
So, the 60th row will have
