What times xxx gives us yyy?

Hint #22 / 3

If we multiply each xxx-value by \blueD{7}7start color #11accd, 7, end color #11accd, we get to each corresponding yyy-value:

y=\blueD{7}xy=7xy, equals, start color #11accd, 7, end color #11accd, x

Hint #33 / 3

The constant of proportionality (r)(r)left parenthesis, r, right parenthesis in the equation y=rxy=rxy, equals, r, x is \blueD{7}7start color #11accd, 7, end color #11accd.
