Solve this inequality for t: 74 - 0.8t < 10 Write the solution in set-builder notation and graph the solution set on a number line.

I need to know how to solve the problem, if you can show me the work it would be great c:

The jewelry store is having a sale. necklaces that were regularly priced at $23.50 are on sale for $18.80. what is the percentage of decrease in the price of necklaces?

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
