Q:
# Karin is also in Mr. Whittaker’s science class, and she recorded the variation in water level at a different part of the river. Karin observed that the water level there fell 1.68 millimeters per year for 1.5 years. Which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river?1.5(-1) + 0.681 + (0.5)(-1)(0.68)(-1.68)(1) + (-1.68)(0.5)1(-1) + 0.5(-0.68)

Accepted Solution

A:

Answer:The correct answer option is c) (-1.68)(1) + (-1.68)(0.5).Step-by-step explanation:Fell in water level per year = -1.68 millimetersFell in level of water in 1.5 years = -1.68 × 1.5Showing this expression according to the distributive property:[tex]-1.68 \times 1.5[/tex][tex]-1.68 \times (1.+0.5)[/tex][tex](-1.68 \times 1).+(-1.68 \times 0.5)[/tex][tex](-1.68)(1).+(-1.68)(0.5)[/tex]So the expression (-1.68)(1).+(-1.68)(0.5) shows a way to use the distributive property to solve for the total variation in water level at this part of the river
