Answer:
Step-by-step explanation:
w / h = u / HG
w = 8
h = 48
u = 5
lets use h / w = HG / u this is the same relationship but looks easier to me
48/8 = HG / 5
6 = HG / 5
6 * 5 = HG
30 = HG
not too tuff... when you set the relationship so it's easiest :)
and yes.. we cold have swapped the fractions and done it the other way and gotten the same answer.. but maybe with a bit more algebra.. and... avoid extra algebra ... that's where the mistakes can be made :P
