Answer:
blank one(planet) 1.=7
Blank two(helmet) 2.=4
Blank three(rocket ship 3.=11
Step-by-step explanation:
the first set of picture is a group of three and 7+7+7 = 21 so each planet =7
The second is a helmet and a plane and we already know the planet =7 so that leaves the helmet, which equals 4 because in the third set it is the helmet and the planet which =11 and 7+4=11 so its 4 for the helmet
The second set determines what the number is for the rocket which is 11 because the planet =7 and the helmet =4 and 7+4 is equal to 11. Hope this indeed helps you.
