Which sum could be used to find the difference in thickness (in inches) between sheeting a and sheeting b. a= 1 7/20 b= 2 3/20

a: (-2 3/20)+(-1 7/20)

b: 2 3/20+ 1 7/20

c: 2 3/20 + (-1 7/20)

d: (-2 3/20) + 1 7/20

X+ y = 5 ; x - y =3 solve using linear combination

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
