5). Radius = 6 km. Circumference = 12π km. Area = 36π km²
6). Diameter = 8 mm. Circumference = 8π mm. Area = 16π mm²
Answer: 9.6
Step-by-step explanation: A rational number can be written as a ratio of two integers (9.6 can write as 96/10)
When you divide fractions, you want to use keep change flip.
You keep the 1st fraction, change the division sign into a multiplication sign, then flip the last fraction.
Let’s use 3/4 ÷ 2/3
Keep 3/4 the same, change the division sign into a multiplication sign, and flip 2/3 so that it is 3/2
It’ll look like this
3/4 x 3/2
Now just multiply the numerators, 2 x 3, then multiply the demoninators, 4 x 2.
You get 6/8
Simplify this number and you get 3/4.

B. x < -4
-2(3x + 6) > 4(x + 7)
-6x - 12 > 4x + 28
-10x > 40
X < -4
It would be: 30/42 = 15/21 = 5/7
In short, Your Answer would be 5/7
Hope this helps!
