Reflection, i am guessing
Problem: 2/3= 18/(x+5)
First, I would multiply the (x+5) over
Making it 2/3(x+5)=18
Second, I would Divide by 2/3 (which is the same as multiplying by the reciprocal 3/2)
which shows up like this now (x+5)=18*3/2
third I would subtract the 5 over
which will give you your answer
Volume of sphere = 4/3 x pi x r^3
Volume of large sphere:
4/3 x 3.14 x 14^3 = 11488.21 cubic cm
Volume of smaller sphere:
4/3 x 3.14 x 2^3 = 33.49 cubic cm
Number of small spheres = volume of large sphere/ volume of small sphere
11488.21 / 33.49 = 343.03
Round to 343 small spheres
