Using the Order of Operations, consider what operations are being done to the variable "c". They are • divide c by 4 • add -5 to the quotient.
To find the value of "c", we "undo" these operations in reverse order. To undo the addition of a number, we add the opposite of the number. So, we will first • add 5 to the equation This gives
Now, the next operation that we need to undo is the division by 4. We can undo that by multiplying the equation by 4. So, we will next • multiply the equation by 4 This gives
Its already filled 5 gallons. if it's 1/4 per minute, then in 4 minutes 1 gallon will be filled. that means in 16 minutes it will be filled 9 gallons because 4 minutes x 4 is 16 minutes and 1 gallon times 4 is 4 gallons and 4 gallons + 5 gallons is 9 gallons ur welcome
