Answer:
- 2.5
Step-by-step explanation:
Note that the absolute value function always returns a positive value, that is
| - a | = | + a | = a
Given
10 - | x - 20 | ← substitute x = 7.5 into the expression
= 10 - | 7.5 - 20 |
= 10 - | - 12.5 |
= 10 - 12.5
= - 2.5
Note that absolute value changes a value to a positive number regarding it's sign.
= 10 - |x - 20|
= 10 - |7.5 - 20|
= 10 - |-12.5
= 10 - 12.5
= -2.5 (Answer)
