Solve the compound - 20 ≤ 2x - 20 ≤ 10

0≤ x ≤ 15

Step-by-step explanation:

- 20 ≤ 2x - 20 ≤ 10-20 + 20 ≤ 2x - 20 + 20 ≤ 10 + 20       ⇒ add 200 ≤ 2x  ≤ 30                                          ⇒ divide by 20≤ x ≤ 15                                               ⇒ answer

or x = [0,15]

Ai just took the test

Ithink it’s b because it say 3 plastic rings and all the balls
