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?
a) 1.5(-1) + 0.68
b) 1 + (0.)(0.68)
c) (-1.68)(1) + (-1.68)(0.5)
d) 1(-1) + 0.5(-0.68)

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 millimeters

Fell in level of water in 1.5 years = -1.68 × 1.5

Showing this expression according to the distributive property:

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

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
