Final answer:
To find the length of the Slime Slip, set up an addition equation: x + 7 = length of Water Whip. Solve the equation to find that the length of the Slime Slip is 7 feet less than the length of the Water Whip.
Step-by-step explanation:
To find the length of the Slime Slip, we can set up an addition equation. Let's assume the length of the Slime Slip is x feet. Since the Water Whip is 7 feet longer, its length would be x + 7 feet. Now we can write the equation: x + 7 = length of Water Whip. Solve the equation by subtracting 7 from both sides: x + 7 - 7 = length of Water Whip - 7. This simplifies to x = length of Water Whip - 7. So the length of the Slime Slip is 7 feet less than the length of the Water Whip.
