One batch of pancakes calls for 3/8 cup of wheat flour and 4/8 cups of white flour . how much flour is needed for three batches of pancakes ?

1  1/8 cups of wheat flour

1  4/8 or 1  1/2 cups of white flour

if you add both cups together then 2  5/8 cups of flour

Step-by-step explanation:

3*3=9 so 9/8 -> 1  1/8 cups of wheat flour

4*3= 12 so 12/8 -> 1  4/8 or 1  1/2 cups of white flour

look a the sides they are perpendicular

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
