3(77/2-5/2y)+7y=111
the answer should be 9 but i don’t know the steps to get to it

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.

Type the next three numbers in a sequence 80, 90, 85, 95, 90, 100, 95, 105
