Aseal went 15 feet below sea level to catch a fish. a sea lion dove 6 feet less than two times as deep as the seal to catch a larger fish. what expression represents the sea lion's position in relation to sea level? 2 times 15 minus 6 15 minus 2 times 6 2 times (negative 15) minus 6 2 times (negative 15) minus (negative 6)

is the sea lion's position in relation to sea level

Step-by-step explanation:

Given:

Distance of seal below the sea level = 15

Distance of lion below the sea level = 6 feet less than two times as deep as the seal

To Find:

Expression representing the sea lion's position in relation to sea level = ?

Solution:

Distance of lion below the sea level = 6 feet less than two times as deep as the seal

Two times as deep as the seal

=>

=>

But it is 6 feet lesser

=>

Since it is below the free level, we use negative symbol

So the position of the lion in relation to the sea level is

=>

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
