Chantelle's cat is 3 inches shorter than 1 / 2 the length of her dog. if her dog is d inches long which expression can be used to determine the length of her cat? a d/2-3 c 3-d/2b d/2+3. d 3+d/2 a carnival charges $ 5 per person to enter. if the carnival made $ 450 from entry fees, which equation could be used to determine how many people ( p ) entered the carnival? a 5-p = 450. c 5×p = 450b 450 × p = 5. d 450-5= prase fast (6th grade math)

Are you sure these are the answer choices? I would think that a valid expression is 1/2d - 3. If you think about it, 3 inches shorter than 1/2 of 3 is basically 1/2 of d minus 3, which is 1/2d - 3. So, I'm not sure if those are the correct answer choices. Of course, you are still able to manipulate that expression.

Now for the next one, since each ticket costs $5 per person, and there was $450 total made, we can put that as 5 times p= 450, which is C. 

Hope this helped! I'm sorry about the first one, but I'm pretty sure I'm right.

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
