This list shows the ingredients needed to make 8 pancakes. 240g plain flour, 2 eggs, 600ml milk. dan wants to make 12 pancakes. what quantity of each ingredient should he use?

To make 12 pancakes Dan should use: 360 g of plain flour, 3 eggs and 900 ml of milk

Step-by-step explanation:

To make pancakes it is required plain flour, eggs and milk.

Dan uses 240 g of flour, 2 eggs and 600 ml of milk to make 8 pancakes.

Now, he wants to make 12 pancakes. We need to calculate the materials required to make them.

We can use a factor to calculate the amount required. We can divide the material in 8  and multiply by 12. The result will be the materials required.

Flour:

240 * (12/8) = 360 g of flour.

Eggs:

2 * (12/8) = 3 eggs

Milk

600 * (12/8) = 900 ml of milk.

Finally, we can conclude that To make 12 pancakes Dan should use: 360 g of plain flour, 3 eggs and 900 ml of milk.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
