63/8 is 7.875, or 7 remainder 7.
Answer: Both plants grow at same rate ie., 4/3 cm per day
Step-by-step explanation:
8 cm = 6 days
1 day = 1/6 x 8 = 4/3 cm
12 cm = 9 days
1 day = 1/9 x 12 = 4/3 cm
This is because astronauts can't sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut's eyes, mouth or nose. Astronauts eat three meals a day: breakfast, lunch and dinner.
Subtract 6x over so you have y - 6x = 11, and 2y - 4x = 14. This is a system of equations. Multiply the first equation by 2 to get 2y - 12x = 22. By subtracting the second equation from the first, you get 8x = -8. So, x = -1. Plug that into the first equation and y = 5. Plug both of those answers into the equation to check. 2(5) - 4(-1) = 14, 14 = 14. The answers y = 5, and x = -1 check out.
