Answer:
55 pirates for 5 ships, 121 pirates for 11 ships
Step-by-step explanation:
for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121
