3(g-3)=6
3g-9=6
3g=15
g=5
that's the answer
Answer:
<em>Sali's speed was 18.75 km/h.</em>
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As,
, so the speed of Jane will be: 
Suppose, the speed of Sali is
km/h
Sali caught up with Jane when they had both cycled 30 km.
So, <u>the time required for Jane to cycle 30 km</u>
and <u>the time required for Sali to cycle 30 km</u> 
Given that, Sali started to cycle 4 minutes or
after Jane started to cycle. So, the equation will be.......

Thus, the speed of Sali was 18.75 km/h.
Answer:
done same as before put value and do process like simplify
Answer:
Step-by-step explanation:
Volume of a cylinder = pi*(xx)^2*yy
= x^4*pi*yy
Volume of a cone = 1/3*pi*(9x^2)^2*h
= 27pi*x^4*h
x^4*pi*y^2 = 27pi*x^4*h
h = y^2 / 27
