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
11/8 is improper
Proper form would be 1 3/8
Yes they are equivalent to each other
-10x - 15y = -30
-10x + 30 = 15y
(30 - 10x) / 15 = y
(30/15) - (10x/15) = y
2 - 2x/3 = y
Answer: y = -2x/3 + 2 or y = 2- 2x/3
