Answers

Answer 1
Answer: 5n + 6 ≥ 21 would be the way to write this in math language.

It says that 5n + 6 is 21 or is more than 21.  The symbol ≥ says 21 or more in this case.

During his tennis career in singles play, John won 3 fewer tournament A titles than tournament B titles, and 2 more tournament C titles than tournament B titles. If he won 17 of these titles total, how many times did he win each one? How many A titles
How many B titles
How many C titles

Answers

A = B - 3
C = B + 2
B = B

(B-3) + (B+ 2) + B = 17
3B - 1 = 17
B = (17+1)/3 =6
A = B-3 =6-3=3
C=B +2=6+2=8

Answer :
3 A titles
6 B titles
8 C titles

If U=pi(r+h),find r when U=16 1/2 and h=2
solve this question by taking the value of pi 22/7

Answers

U=π(r+h)
r+h=U/π
r=U/π  - h

Data: 
U=16  1/2=16  +  1/2=(16*2+1)/2=33/2
h=2
π=22/7

Then: 
r=U/π  - h
r=(33/2)/(22/7)   -   2
r=(33*7)/(2*22)   -   2
r=231 /44   -   2
r=(231-2*44)/ 44
r=(231-88)/44
r=143/44   =   (3*44  + 11)/44=3  11/44

Answer: r=143/44      or    3  11/44
U =  π* (r + h )   [ : π

(U)/( \pi ) = r + h \n \n r = (U)/( \pi ) - h \n \n r = (16,5)/( \pi ) - 2 \n \n r = (165)/(10) : (22)/(7) - 2 \n \n r = (33)/(2) * (7)/(22) - 2 \n \n r = (3)/(2) * (7)/(2) - 2 \n \n r = (21)/(4) - 2 = 5,25 - 2 = 3.25 Answer r = 3,25
