133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
Answer:
28.1
Step-by-step explanation:
You can answer questions like this by working backwards.
To do this we can divide 78.2 by 2 and that gets us 39.1
Now we have to subtract 11 from it and that gets us our final answer:
28.1
21 + 20 = 43
Total is 123, so divide by 43.
123/43 = 2.86 rounded to 3.
(females) 20 x 3 = 60 female lions
