Answer
You need at least 8.3 points for the armstand dive in order to qualify.
Work Step by Step
Step 1) 44.7 + x ≥ 53 ... 44.7 is the total score you have
Step 2) x ≥ 8.3 ... At least 8.3 is needed in order to qualify.
44.7 + x ≥ 53
x ≥ 8.3 So far the dive scored a total of 44.7 however in order to qualify for the regional diving competition you need a total of 53 points. You need at least 8.3 points for the armstand dive in order to qualify.
