Answer:
x=9
Step-by-step explanation:
Remove the radical by raising each side to the index of the radical.
So men to women=3 to 4
210 men
210 represents 3 units
wome=4
210=3 units
divide by 3
70=1 unit
multiply by 4 to find women
280=women
total workers=women+men
women=280
men=210
280+210=490
total =490
The inverse of an implication p ⇒ q is ¬p ⇒ ¬q.
The converse of p ⇒ q is q ⇒ p.
The contrapositive of p ⇒ q is ¬q ⇒ ¬p.
Then
• the inverse of the inverse of p ⇒ q is p ⇒ q
• the inverse of the the converse of p ⇒ q is ¬q ⇒ ¬p
• the inverse of the contrapositive of p ⇒ q is q ⇒ p
