We eat food, like the chicken and dumplings, for nutrients and energy. once your food is digested, what body system works to move the nutrients from your food to all the various parts of your body? a) muscular system b) excretory system c) respiratory system d) cardiovascular system

The correct answer would be D)  cardiovascular system.

The cardiovascular system of the body consists of pumping organ that is, heart, blood vessels (arteries, veins, and capillaries), and transporting medium which is blood.

It is the main system which helps in transportation of oxygen, nutrients, and hormones throughout the body. In addition, it helps in the removal of metabolic wastes such as carbon dioxide and nitrogenous wastes.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
