Question

Cooper is measuring ingredients for his special dessert. He needs a total of 70.4 mL of milk and melted butter. The recipe calls for 30.6 mL of butter. How much milk, m, does Cooper need for his recipe?

Answer 1

70.4 = 30.6 + m
solve
subtract 30.6 from both sides
39.8 = m

He needs 39.8 mL of milk for a the dessert.

 To check: 30.6 + 39.8 =?= 70.4
70.4 = 70.4

Hope this helps :)

Answer 2

Answer:

Cooper needs 39.8 ml of milk for this recipe.

Step-by-step explanation:

Cooper needs a total of 70.4 ml of milk and melted butter for a special dessert.

Let m be the amount of milk and 30.6 ml of butter be needed to prepare a dish then

m + 30.6 = 70.4

m = 70.4 - 30.6

m = 39.8 ml

Therefore, Cooper needs 39.8 ml of milk for this recipe.
