Question

Suppose that Cecil, the tightrope walker, can only travel lengths of 5 feet, 6 feet, and 8 feet.

• He can travel forward (positive 5, 6, 8)
• backward negative (-5, -6-8)
can go past the ladder and come back.
.
Show TWO number expressions that will represent a way for Cecil to cross a tightrope of 12 feet. ONE way MUST use a negative.

Answer 1

Cecil can cross a tightrope of 12 feet using a combination of forward and backward steps. Two number expressions that represent these ways are: Positive 5 + Negative 5 = 0 and Positive 8 + Negative 8 + Positive 6 = 6.

Step-by-step explanation:

To cross a tightrope of 12 feet, Cecil can use a combination of forward and backward steps. Here are two number expressions:

In the first expression, Cecil can take a positive 5-foot step forward and then a negative 5-foot step backward, resulting in a total distance of 0 feet. This means he stays in the same spot.

In the second expression, Cecil can take a positive 8-foot, then a negative 8-foot, and finally a positive 6-foot steps. This would result in a total distance of 6 feet.
