Let w=23 . what is the value of w + 45 ?

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
