13. A number half of that number end one-third of that number are added. The result IS 22. What 15 the number
2 answers:
X=is the number looked for.
x/2=is the half of "x".
x/3=is the one-third of the "x".
We suggest this equation:
x+(x/2)+(x/3)=22
Least common multiple=6
6x+3x+2x=132
11x=132
x=132/11=12
Te number is 12
To check:
A number (12)+ half of that number (6)+ the one-htird of that number(4) is:22
12+6+4=22
Let the no. be x
x+x/2+x/3=22
6x+3x+2x/6=22
11x/6=22
11x=132
x=12

D.)x/10=12/15
x=8
A.)x/2+x/6=7
x=21/2 or 10.5 or 10 1/2
B.)x/9+2x/2=1/3
x=3/10 or 0.3
Irrational will be the answer
I could be wrong but i believe it's six
let the height be x then
base of island = x/2
area of island = 1/2* x/2* x = x2 / 4 = 576m
