Answer:
Unit cost: $2.50 per potato
Step-by-step explanation:
Set up a proportion:
<h2><u>5 potatoes</u> = <u>x potatoes</u></h2><h2>2 dollars 1 dollar</h2><h2 />
cross multiply:
2x = 5
divide by 2 on both sides
x= 5/2 or 2.5
The width of the sidewalk would be 10ft.
Sorry if incorrect
Remember 2 negatives make a positive. And two Positives make a negative
Reflections across the x-axis leaves the x coordinates the same but the y coordinates change sign
so point P (2,-12) is reflected to (2, 12)
So now you can identify the correct choice
