Lamont has purchased 20 trading cards and wants to have at least 50 trading cards. Write and solve an inequality to find the number of trading cards Lamont needs. Select all of the true statements.
x + 20 >= 50
x + 20 <= 50
x >= 30
x <= 30
x >= 70
answer CORRECTLY
The correct inequality is: x + 20 ≥ 50.
If we solve this inequality, we subtract 20 from both sides:
x ≥ 30.
Thus, the correct statements are:
x + 20 ≥ 50
x ≥ 30.
