Answer:
x = 11
Step-by-step explanation:
∠BCE + ∠ECF = 180°
∴(10x + 15)° + 5x° = 180°
(15x + 15)° = 180°
15x = 180° - 15°
15x = 165°
x = 165°/15°
x = 11°
Answer:
x<4
Step-by-step explanation:
To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.
First, expand 4(x-3).
This will obtain:

Now, shift x terms and integers on each side.

After simplifying, it will get:

Finally, we can solve for x.

We can also draw the respective graph (please don't mind my drawings), where the area shaded in green is the range.
