Alloys are made by mixing metals. Two different alloys are made using iron
and lead.
To make the first alloy 3 cubic centimetres of iron and 4 cubic centimetres of
lead are used . This alloy weighs 65 grams.
a) Let x be the weight of 1 cubic centimetre of iron and y be the weight of 1
cubic centimetre of lead – write an equation using x and y which satisfies
this condition.
To make the second alloy 5 cubic centimetres of iron and 7 cubic centimetres of
lead are used. This alloy weighs 112 grams.
b) Write an equation using x and y which satisfies this condition.
c) Find the weight of 1 cubic centimetre of iron and 1 cubic centimetre of lead.
