Alright, so we can start by writing it out by their signs.
Using PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) and noting that the inequality comes last, we can write it as the sum of (addition), then three times (multiplication) a number and 4 (ties in with the sum of, making it also addition).Note that we know that "a number and 4" means addition because it doesn't state to do anything with it, and we don't know what "the sum of" referred to with numbers, so they match up. Therefore, we have multiplication (3 times a number=3 * number), then addition (3 times a number, or 3 * number, added to 4, or 3*number+4), and we can do the inequality. Between -8 and 10 means that it is greater than -8 and less than 10, as 10 is the larger number, writing it out as -8< (less than) 3*number+4 < (3*number+4 is less than 10, so we have another less than sign) 10. Subtracting 4 from everything using the subtraction property of equality, we get -12<3*number<6. Next, we can divide everything by 3 to separate the number and get -4<number<2.
Feel free to ask further questions!
1/n^2 and n^-2 are the same, and 16 and 1/16 definitely aren’t the same 4^-2 is just -4 * -4, and because negative * negative = positive, that adds up to being 16.
The answer is 1/16.
Answer:
you'd get 0 because anything multiplied or divided by 0 is 0

Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make 
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make 
flowers in an hour.
The groups decided to work together. They can make 
together in an hour and it takes them 
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,
