Answer:
55-4x=22
Step-by-step explanation:
We want to know how long it'll take until 22 mints are left, so we already have the "=22" part.
Customers are taking 4 mints per hour, so the number is subtracting. So now we have "-4=22".
The 4 is being taken from the 55 mints <u>per hour</u>, so 4 is multiplied by "x", so now the equation is "-4x=22".
The final equation would be
55-4x=22.

D. -x2 + 2x -3
the first step is we open all the brackets then it will be :
x2 - 3x - 2x2 + 5x - 3
= x2 - 2x2 - 3x + 5x - 3
= -x2 + 2x -3
Answer: 1 and 4 are correct
Step-by-step explanation: good luck!
