Brianna is putting a border around her garden. She wants to make it in the shape of an isosceles triangle. Brianna has 110 inches of border. She wants the base of the triangle to be 10 inches shorter than triple the length of the two equal legs. Create a pair of linear equations in two variables that represent this problem. Let l represent the two equal legs of the triangle, and let b represent the base of the triangle.(1 point)

2l+2b=110; b=3l−10
2 l plus 2 b equals 110 ; b equals 3 l minus 10

2l+b=110; l=3b−10
2 l plus b equals 110 ; l equals 3 b minus 10

2l+b=110; b=3l−10
2 l plus b equals 110 ; b equals 3 l minus 10

2l+b=110; b=3l+10

Answer 1

2l+2b=110; b=3l−10
2 l plus 2 b equals 110 ; b equals 3 l minus 10
