Change the following sentence from passive voice to active voice. The dog is being walked by Katie.
Katie is walking the dog. To make passive voice active, we make the sentence structure follow this order: Subject, action, object. By making Katie the subject, Katie is now performing the action (walking) to the object (the dog).
Fill in the blank with the correct choice in the parentheses. Johnny and Melissa left ___ (their, there, they're) ball over ___ (their, there, they're).
Johnny and Melissa left their ball over there. The first blank is "their" because "their" shows ownership. Johnny and Melissa have ownership over the ball so we use the word "their." The second blank is "there" because "there" means at that place. Johnny and Melissa left their ball over at that place, so we use "there." Neither blank would be "they're" because "they're" is a contraction of "they are." This would not make sense in the sentence because "left" is the verb.
Simplify the following algebraic expression: 3xy+5x+7y-2xyz+6y+8xyz+xy
To simplify 3xy+5x+7y-2xyz+6y+8xyz+xy, we must combine like terms. -2xyz+8xyz = 6xyz 3xy+xy = 4xy 5x = 5x 7y+6y = 13y We then write the simplified equation as 6xyz+4xy+5x+13y. There are no negatives in the answer because after combining like terms none of the terms are negative.
