Answer:
u= 11.4
Explanation:
8/7 = u/10
we are trying to make u the subject of this equation
so we want u by itself
firstly:
multiple both sides by 10
(8/7) × 10 = u/10 ×10
the 10s on the right side cancel each other and we are left with u
This is the equation NOW
10(8/7)=u
Secondly:
Let's solve for u
10/1×8/7=80/7
=11.428
rounded to the nearest tenth is 11.4
Therefore
u= 11.4
