An oil drilling company is drilling a hole. the elevation of the bottom of the hole changes by feet each day. after a certain number of days, the bottom of the hole is at an elevation of feet. which equation can be used to find x, the number of days they drilled?

option.D

Step-by-step explanation:

each day it changes by so for two days , the elevation becomes   +  for 3 days :   +   +  so, for n days,   + ........ n times

=  n*

therefore, for x days, elevation = x*as it is given that after certain days this elevation has reached so, x* =

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
