The slope is -½, and the y intercept would be (0, -5/2)
So all of the internal angles of a triangle will add up to 180 degrees. So if we add all of the expressions given and set them equal to 180, we can solve for x, then solve for each angle...
(2x + 1) + (3x - 3) + 9x = 180
2x + 3x + 9x + 1 - 3 = 180
14x - 2 = 180
14x = 182
x = 13
Now we can substitute 13 into each expression to find the value of each angle...
2x + 1 =
2(13) + 1 =
26 + 1 = 27 degrees
3x - 3 =
3(13) - 3 =
39 - 3 = 36 degrees
9x =
9(13) = 117 degrees
So the 3 angles are 27 degrees, 36 degrees, and 117 degrees.
The smallest is 27 degrees
** Note-- I don't see 27 degrees in the answer choices you gave, so I double checked my math (I didn't find any mistakes). Please check to see that the question is written correctly (pay close attention to plus and minus signs).
8 liters of club soda was used. The total was 18 liters and one third was orange juice. So you would divide 18 by 3 which equals 6. 6 liters of orange juice + 4 liters of the punch = 10 liters. 18 - 10 = 8.
Here’s the step of doing it
I think it would be C B and E for number 1 and for the second problem 78 one and 263 thousandths, the next is 782 tenths and 63 thousandths, and 78263 thousandths for the last one. Correct me if I am wrong.
