Answer:
How many apples are in each pie if a total of 3 and one-half apples were used to bake 2 pies?
Step-by-step explanation:
Use process of Elimination: How do you solve each of these questions and which one uses division?
1. How much does it cost to buy 3 and one-half pounds of apples at $2 per pound? = 3.5 x 2 = $7
2. How many apples are needed for 2 pies if the recipe uses 3 and one-half apples per pie? = 2 x 3.5 = 7 apples
3. How many more apples are needed if a recipe uses 3 and one-half apples and you only have 2 apples? = 3.5 - 2 = 1.5 apples
4. How many apples are in each pie if a total of 3 and one-half apples were used to bake 2 pies? = 3.5 divided by 2 =1.75 apples.
Note: Questions 1 and 2 used multiplication, Question 3 used subtraction and it was only question 4 that needed any division at all.
Hope this Helps,
Good Luck

Answer: mannn i dunno either i’m tryna figure out the same thing
Step-by-step explanation:
B = (-9 + (-1) /2) (-4 + 6 /2)
B = (-9-1/2) (2/2)
B = (-10/2) (1)
B = (-5) (1)
B = (-5,1)
E = (x1 + x2 / 2) (y1 + y2 / 2)
E = (-5 + x2/2) (1 + y2 / 2)
(-4, -3) = (-5 -3/2) (1 -7/2)
(-4, -3) = (-8/2) (-6/2)
(-4, -3) = (-4) (-3)
(-4, -3) = (-4, -3)
D (-3, -7)
