Using only a compass and a straightedge, you are constructing a line perpendicular to and passing through a given point, m, on . with a compass of set width, you have drawn arcs that intersect on each side of m and marked the two intersection points as p and q. the next step in this construction is to place the compass needle on a. p and sets its width to m b. m and sets its width beyond p c. p and sets its width beyond m d. m and set its width to half the distance between p and m , you

20y5 times 2 is 1010 times -2 is -20, plus y

It is e) i am not sure if you have any questions or need any

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 : )
