Answer:
Option A. 3.5x + 15 ≥ 55
Step-by-step explanation:
Points Rosh received for becoming a member = 15
Points Rosh received for visiting the moving theater = 3.5
Total points needed for a free movie ticket = 55
For each visit he receives 3.5 points, so for x visits he will receive 3.5x points.
Total points = Points received on becoming a member + Points received on x visits
So,
Total Points = 15 + 3.5x
These points must be at least 55 for a free movie ticket. At least means equal to or greater than. So the total points must be equal to or greater than 55 in order to earn a free movie ticket. This can be expressed as:
3.5x + 15 ≥ 55
So, option A gives the correct answer
Answer:
17.60
Step-by-step explanation:
Look at the room carefully, the length of the room is 11 feet
And the height = 10 feet
The area of the 4 walls of the room = 4( 11×10) = 440 sq ft
Area covered by each roll = 25 sq ft
= 440/25 = 17.60 rolls
Therefore we require 17.60 rolls to cover a rectangular room on all four sides.
