Answer:
12
Explanation:
Basically all you have to do is 60 divided by 5. There are 5 hexagons (u) of equal weight, and their weight equal to 60. This can be rewritten as 5u= 60.
u = 12
The equation is showing 5(u) = 60
Begin: 5(u)= 60
2. Divide the 5 from both sides to get the u-value alone.
a) 5u/5 = u b) 60/5 = 12
Now: u = 12
