You would fill in 9 for x so your equation would be 2(9)+3 and you would then get 21. Therefore the answer is f(x)=21
21 out of 28 cookies are chocolate chip
I can't exactly understand what you mean but what I thought you put in the answer is 40
1) 8
2) 14.5*2=29
3) 7x+5=2*13, 7x+5=26, 7x=21, x=3
4)d(1)=2r,
if r increase 3 times, d(2)=2*(3r)
d(2)/d(1)=(2*3r)/2r=3,
so diameter increases 3 times
Answer:
C)
Step-by-step explanation:
Find the total sum
25+28= 53
53+31=84
Fimd the average by dividing by 3
84/3= 28
Hence, the answer is c
