Juan owns a tree cutting machine service. For every 3 hours of tree-cutting, Peter charges $25.50. Select the equation that models the relationship between the total charge, y, and the number of hours, h, worked.
A. $25.50= 3h B. y= (3+h) - $25.50 C. y = 76.5h

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.

What is the radical expression that is equivalent to the expression 27 1 over 5?
