Please help In an effort to make students aware of the health risks of obesity, Kelly is teaching about nutrition. She teaches that a person who weighs 128 pounds should aim to consume 36 grams of protein and 2,200 calories each day.
An egg contains 6 grams of protein and 77 calories. A 6-ounce glass of goat’s milk contains 8 grams of protein and 168 calories.
Assuming someone already ate 1,542 calories and has a total of 658 left to eat for the day, how many eggs and 6-ounce glasses of goat’s milk should that person eat to achieve the daily goal?
THIS IS SYSTEMS OF EQUATIONS

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
