At a movie theater, the ticket prices to see a movie in 3-D are $18 for an adult and $12 for a child. The owner of the theater wants to make at least $300 when a movie is shown in 3-D. Choose the inequality that shows the numbers of tickets that must be sold. A. 18x + 12y > 300 B. 18x + 12y < 300 C. 18x + 12y ≥ 300 D. 18x + 12y ≤ 300

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

i can't solve unless i know what the line is
