Answer:
5/8
Step-by-step explanation:
There are 8 intervals, the tack ends at the 5th interval, so 5/8
2 1/3 = 7/3
Both numbers should be improper fractions.
11/3 + 7/3 = 18/3
Now the fractions must be simplified
18 ÷ 3 = 6
So 11/3 + 2 1/3 = 6
5(x+(x+1)+(x+2))=150
5(3x+3)=150
15x+15=150
15x=135
x=9
Your three consecutive integers are 9, 10, and 11.
Answer:
172
Step-by-step explanation:
(a - b)² = a² - 2ab + b², hence
a² + b² = (a - b)² + 2ab = 12² + (2 × 14) = 144 + 28 = 172
