Jameson wants to save up his money to buy a car. His parents said they will match what he saves, up to $2,000. Jameson mows lawns in the summer, and shovels snow in the winter. He charges #25 per lawn, and #20 per driveway. Let x represent the amount of money that Jameson can save so that his parents will match the amount. Let d represent the number of lawns he mows, and represent the number of driveways he shovels. Which of the following inequalities need to be part of the system? Select all that apply

25l+20d=x
x<=2000
25l+20d 20l+25d=x
x>=2000

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
