Answer: 180, 185, & 190
<u>Step-by-step explanation:</u>
1st #: 5x
2nd #: 5(x + 1)
3rd #: 5(x + 2)
1st # + 2nd # + 3rd # = sum
5x + 5(x + 1) + 5(x + 2) = 555
15x + 15 = 555
15x = 540
x = 36
1st #: 5x = 5(36) = 180
2nd #: 5(x + 1) = 5(36 + 1) = 185
3rd #: 5(x + 2) = 5(36 + 2) = 190
-4= Contraction
2.5=Expansion
2/3= Contraction
-3/4= Contraction
Best way to solve this, if the scale factor is less than one, is a contraction. If it is greater than one, than it is an expansion.

This looks one hundred percent correct to me and to check your answer you can plug in the answer you find to the first equation
17=37+4f
17=37+4(-5)
17=37-20
17=17
great job!!
first put both options into equation format. option 1: 360+75m and option 2: 24(30). solve the easier problem first which is 24 multiplied by 30 which equals 720. so now you know what should be on the side of the equal sign so that they both have eqaul solutions. 360+75m =720. subtract 360 from both sides so that equation turns to 75m=360, then divide both sides by 75 and get 4.8. it would take 4.8 months
