1/6 because the opposite of multiplying is dividing and dividing 6 is equal to multiplying it by the reciprocal, which is 1/6
Answer:
w = 
Step-by-step explanation:
Given
P = 2w + 2h ( subtract 2h from both sides )
P - 2h = 2w ( divide both sides by 2 )
= w
Answer:
f all his animals were pigs, there'd be 880 legs, There are 240 legs missing which represents 120 chickens (so he has 220 - 120 100 pigs.)
Check: (120 x 2) + (100 x 4) = 240 + 400 = 640 QED
