Match the systems of equations to their solutions.

x = 2, y = 7 - - ->

x = 5, y = 2 - - ->

x = 3, y = 5 - - ->

x = 7, y = 3 - - ->

Choices:
1 . 2x + y = 12
x = 9 − 2y
2.
x + 2y = 9
2x + 4y = 20

3.
x + 3y = 16
2x - y = 11

4 y = 11 − 2x
4x − 3y = -13

5. y = 10 + x
-3x + 3y = 30

6. 2x + y = 11
x - 2y = -7

Volume of a cylinder with a radius of 13 in and height of 30 in

The track team ran a mile and a quarter during their practice how many kilometers did her team runs?

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.
