To win a trivia contest, Oscar must score more than 400 points.  He earns 12 points for each right answer and loses 4 points for each wrong answer.  Create the inequality that represents the number of right answers, R, and wrong answers, W, Oscar can give to win the contest.

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 60 calories from p grams of protein and f grams of fat. The equation 4p + 9f = 60 represents the relationship between these quantities.  Determine if each pair of values could be the number of grams of protein and fat in the snack. Be prepared to explain your reasoning. 5 grams of protein and 2 grams of fat 10.5 grams of protein and 2 grams of fat 8 grams of protein and 4 grams of fat If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning. In this situation, what does a solution to the equation 4p + 9f = 60 tell us? Give an example of a solution.

In this situation, what does it mean when we say that x = 12 and y = 1.5 are not solutions to the equation? How did you find out the grams of protein in the snack given that there are 6 grams of fat? Can you find another combination that is a solution? How many possible combinations of grams of protein and…

The average starting salary for an editor at a techs company is 39,800 the actual salaries can vary by less than 1300 which inequality can be used to determine whether salary X falls within this range what is the range of the starting salaries of the company

Due to the drought in California, many communities have tiered water rates. There are different rates for Conservation Usage, Normal Usage and Excessive Usage. The usage is measured in the number of hundred cubic feet (hcf) the property owner uses. During the winter, a property owner will pay $24.72 plus $1.54 per hcf for Normal Usage. The bill for Normal Usage would be between or equal to $49.36 and $86.32. How many hcf will he be allowed to use if he wants his usage to stay in the normal range?

Due to the drought in California, many communities now have tiered water rates. There are different rates for Conservation Usage, Normal Usage and Excessive Usage. The usage is measured in the number of hundred cubic feet (hcf) the property owner uses. During the summer, a property owner will pay $24.72 plus $1.32 per hcf for Conservation Usage. The bill for Conservation Usage would be between or equal to $31.32 and $52.12. How many hcf can the owner use if she wants her usage to stay in the conservation range?

The top three countries in oil consumption in a certain year are as follows: the United States, Japan, and China. In millions of barrels per day, the three top countries consumed 39.8% of the world's consumed oil. The United States consumed 0.7% more than four times China's consumption. The United States consumed 5% more than triple Japan's consumption. What percent of the world oil consumption did the United States, Japan, and China consume?[27]
