Answer:
2
Step-by-step explanation:
The easiest thing is to convert it to an improper fraction.
-2 1/9 turns into -19/9. -4 1/9 turns into -37/9.
-19/9 - (-37/9) here you would add because you are subtracting a negative number.
-19/9 + 37/9 change it to positive and then add.
-19+37=18
it was 18/9. that simplified is 2.

Answer:
C
Step-by-step explanation:
4(8-x)=8
32-4x=8
-4x=-24
x=6
The absolute value of -3 is 3 and -3 so both would be right
Answer:
The interior angles are 80°, 30° and 70°.
Step-by-step explanation:
The sum of interior angle of a triangle is 180°. Two exterior angle of the triangle is given as 100° and 150°. The exterior angle of a triangle is equal to the sum of the opposite interior angle. The exterior angle is the angle between one side of a triangle .
Since angle on a straight line = 180°
Two interior angles can be calculated as follows
180 - 100 = 80°
180 - 150 = 30°
2 interior angles are known.
Note the sum of interior angle of a triangle is 180°
since 2 interior angle are known the third angle can be calculated as follows
180 - 80 - 30 = 70°
The interior angles are 80°, 30° and 70°.
