What is 11 4/8 - 5 6/8

The distance between two points is 6.5cm and scale of map is 1: 1000 what's the distance between the two points

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
