If the unknown value is x, then x = × 6 = 21.
Explanation:
- Since it is a double number line with a ratio, all the ratios of one number line to the other will remain equal for all the values along both the number lines. Assume the unknown value to be x.
- The ratio of the number on the first number line to the corresponding number on the second number line is calculated to be;
=
=
=
=
= 3.5. So
- We can also calculate x by the following method. As ratios are equal we can directly substitute the value to another ration. So
= 21.

Answer:
D. a ║ b
Step-by-step explanation:
If we figure the other angle of each linear pair, we can directly compare angles to see if corresponding angles are the same. Where they are the same, the lines are parallel.
Line a is parallel to line b.
