Each week 5 new office phones are installed in a major network company. At the beginning of March, 200 phones had already been installed. Write a linear equation to model this situation. Do not use spaces in the equation

Use your equation if the company wanted to replace all phones in the building (500 total). How many weeks would it take to finish this project?

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

if x = 1, then the answer is 3.5

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
