hammers and wrenches are manufactured at a uniform weight per hammer and a uniform weight per wrench . if the total weight of 1 hammers and three wrenches is one - third that of 8 hammers and 5 wrenches , then the total weight of one wrench is how many times that of one hammer ?
"x be the weight of a hammer and y be the weight of a wrench . ( 1 x + 3 y ) = 1 / 3 * ( 8 x + 5 y ) 3 ( 1 x + 3 y ) = ( 8 x + 5 y ) 3 x + 9 y = 8 x + 5 y 4 y = 5 x y = 5 x / 4 ans - d"
divide(subtract(1, multiply(const_3, const_2)), subtract(multiply(const_3, const_2), 8))
