Mike is driving a boat at 12 mph and is increasing his speed by 0.2 mph each second. Hank is driving a boat at 25 mph and is decreasing his speed by 0.7 mph each second. Which of the following equations could be used to determine x, the number of seconds it will take for the boats to be traveling the same speed?

• 12x + 0.2 = 25x - 0.7

• 12 - 0.2x = 25 + 0.7x

• 12.2x = -25.7x

• 12 + 0.2x = 25 - 0.7x

Re-write the equation 2x − 4y = 12 so that "y" is isolated.

• y = 2x − 3
• y = (½)x + 3
• y = ⁻2x− 3
• y= (½)x - 3

Re-arrange the formula
 A= 2πr² + 2πrh
so that "h" is isolated.
[Hint: Remember the butterfly...]

• h = A/(2πr) − r
• h = (2Aπr)/(2πr)
• h = A/(2πr³)
• h = A − (2r)/π
