1. Write and evaluate a subtraction expression to find the depth of the submersible at 2:17 p. m 2. Write and evaluate a subtraction expression to find the depth of the submersible at 2:18 p. m.
3. If the submersible dove straight down, what is the distance between the submersible's starting position at 2:15 and its position at 2:18? Show your work.

The depth of a lake at a certain point, wich is a function of the distance of that point from shore, is 30 feet.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

Which letters from the table represent like terms? a and b b and c a and d b and d
