First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

Ifigured it out from watching a khan academy video , i am so sorry about the first answer. but i agree that x= 72. and now you can give the other person brainliest if you want.

That little box would be 90 degrees. a triangle should be 180 degrees. 90 + 15= 105. 180-105=75. your answer would be 75 degrees but since you asked for the nearest tenth, it would be 80 degrees.
