How do you divide a negative number and a positive number? My problem is -19÷13.

cestrela7 [59]

When you divide a negative and a positive, you don't have to worry about the negative that much. Just divide like normal, and then add the negative at the end. However, if you divide a negative by a negative, it's double negative, and therefore positive. So in the case of -19 / 13, the answer would be negative.

Hope this helps! :)

Gala2k [10]

Answer:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$

Step-by-step explanation:

Let A represent number of adult t-shirts and C represent number of child t-shirts.

We have been given that adults t-shirt are $5 child t-shirt are $2.50, so cost of A adult t-shirts would be $5A$ and cost of C child t-shirts would be $2.50C$ .

We have been given that Jerome need at least 200 adults t-shirt. This means the number of adult t-shirts should be greater than on equal to 200.

We can represent this information in an inequality as:

$A\geq 200...(1)$

We are also told that Jerome will spend no more than $1500 on t-shirt. This means that cost of A adult t-shirts and C child t-shirts should be less than or equal to 1500.

We can represent this information in an inequality as:

$5A+2.50C\leq 1500...(2)$

Therefore, our required system of inequalities would be:

$A\geq 200...(1)$

$5A+2.50C\leq 1500...(2)$
