21 students because if 6 represents 30% u add 6 two more time which equals 18 and 90% then u add 3 more because it is half of 6. when u add 3 more u will get 21 and 100%
Answer:
its pi
Step-by-step explanation:
BB.7 = GX
C = pi * r ^squared
r = is radius
square the radius, multiple by r
or
2 x pi x r
X=11
All you have to do is add 5 to both sides and then divide by 5 on both sides
Let the value of the number be represented as x.
Then, write out an equation;
3x=2x+3 <--- Solve for x now
3x-2x=3
x=3
Therefore the number is 3.
Hope I helped :)
