So the division of a number and -9 or
x/-9
+10=11 or
(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Answer:
40° and 140°
Step-by-step explanation:
A linear pair of angles sum to 180°
let x be one angle then the other is 3.5x and summing gives
x + 3.5x = 180
4.5x = 180 ( divide both sides by 4.5 )
x = 40
one angle = 40° , the other is 3.5 × 40° = 140°
To find the scale factor, simply divide 10 by 8 to get 5/4, or 1.25.
Therefore, the scale factor is 5/4 or 1.25.
Step-by-step explanation:
