Which ordered pair is the solution to the system of equations? {2x−y=−5x+3y=22{2x−y=−5x+3y=22 (7, 19)(7, 19) (8, 21)(8, 21) (4, 9)(4, 9) (1, 7)

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
