Let \(x\) represent the number. Use the given conditions to write an equation. Solve the equation and find the number. The product of 8 and a number is \(272 .\) Find the number.
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Membership in a fitness club costs 500 dollars yearly plus 1 dollars per hour spent working out. A competing club charges 440 dollars yearly plus 1.75 dollars per hour for use of their equipment. How many hours must a person work out yearly to make membership in the first club cheaper than membership in the second club?
According to the American Bureau of Labor Statistics, you will devote 37 years to sleeping and watching TV. The number of years sleeping will exceed the number of years watching TV by 19.

The bar graph shows that average rent and mortgage payments in the United States have increased since \(1975,\) even after taking inflation into account. Exercises \(31-32\) are based on the information displayed by the graph. (GRAPH CANNOT COPY) In \(2008,\) mortgage payments averaged 1514 dollars per month. For the period shown, monthly mortgage payments increased by approximately 20 dollars per year. If this trend continues, how many years after 2008 will mortgage payments average 1714 dollars ? In which year will this occur?
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. The inequality \(-4 x<-20\) is equivalent to \(x>-5\)
