Answer:
4399.98 ft per min
Step-by-step explanation:
- Divide 50 mi by 60 min = 0.83333
- Multiply this by 5280 = 4399.9824 ft per min

I need help!!!! Please!!!!
2. What inverse operation must be performed to isolate the variable? Division
4. the correct expansion of the exponent term 155. None of the above
5. What is the inverse operation that must be performed to solve the equation
x - 15 = 9?
Add 15 to both sides of the equation
6. Select all of the steps that should be performed to solve the equation
(3 points, which means you are to select three options below. No partial credit.)
12 + t = 108
12 - 12 + t = 108 - 12
0 + t = 96
t = 96
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).
