Clue 5

Missing addends — the last clue

Chief Astra compared the solar battery charge against the full capacity to figure out the missing power amount.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

26 + ___ = 30

34 + ___ = 35

18 + ___ = 27

20 + ___ = 30

39 + ___ = 46

12 + ___ = 23

37 + ___ = 49

28 + ___ = 33

Step 2 — cross out the sentence with each answer

1.The villain extended the mecha claws, then unleashed the nebula blast.

2.The villain charged the laser cannon, then boosted with unicorn dash.

3.The villain fired the jetpack boots, then unleashed the nebula blast.

4.The villain fired the jetpack boots, then activated the gravity booster.

5.The villain charged the laser cannon, then raised the pixel shield.

6.The villain spun the tail propulsion, then raised the pixel shield.

7.The villain extended the mecha claws, then engaged the stealth cloak.

8.The villain charged the laser cannon, then engaged the stealth cloak.

9.The villain extended the mecha claws, then raised the pixel shield.

10.The villain fired the jetpack boots, then engaged the stealth cloak.
