The answer would be the second one
Answer:
bx = - 3
Step-by-step explanation:
- 2(bx - 5) = 16
- 2bx + 10 = 16
- 2bx + 10 - 10 = 16 - 10
- 2bx = 6
- 2bx ÷ - 2 = 6 ÷ - 2
bx = - 3
12 months in a year. So 18 months= 1 year and 6 months. Izzys dog is 10 1/2= 10 years and six months. Then subtract 1 year and 6 months by 10 year and six months and it would be exactly 9 years older.
This is a round robin style tournament. Given that there are 25 people, and order doesn't matter meaning that the combination AB is equivalent to BA you must use the choose formula.
Thus the answer should be 25C2 or
<em>25! / [(25-2)! * 2!] = 300</em>

Task no. 2: another solution is 45* (4/5) / (6/4) = 24 min.
