Erin and jamie are collecting shells while the tide is out. erin has 27 shells, and she has 9 more than jamie. write and equation for this situation and find how many shells jamie has collected. a. 27 = j + 9; jamie collected 18 shells b. 27 = j – 9; jamie collected 36 shells c. 27 + 9 = j; jamie collected 36 shells d. 27 = j + 9; jamie collected 36 shells

A.

Erin's total minus 9 gives us Jamie's total. This means Erin's total equals Jamie's total plus 9. This leads us to the conclusion that 27 (E's total) = j + 9 (the difference). We also know from the first phrase that E - 9 = j, meaning 27 - 9 = j, so j = 18.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
