Christi alters a skirt. She cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge. Which expression best represents the final length of the skirt?

Sagot :

Answer: ( x -2 ) inches

Step-by-step explanation:

Let x  = length of skirt.

Given: Christi first cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge.

Cutting of length will be represented by a negative integer.

The expression best represents the final length of the skirt = x-7+5 inches

= x -2 inches

Hence, the expression best represents the final length of the skirt = ( x -2 ) inches
