. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127

2s-12=j

S+J=127

Step-by-step explanation:

ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j

. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127
