Answer:
12 pies
Step-by-step explanation:
To solve this problem, the best method will be to use a proportion! To set this proportion up, you must understand the values that the problem is giving you. The problem states that 7 cups of flour makes 3 pies. This wording tells us that those two values will both be on one side of the proportion. It does not matter which value is on top or bottom, as long as they are together on one side! For this problem, I'll set up the left side of the proportion like this:
Next, you'll include your third value and your x on the right side of the proportion. Make sure that your third value aligns with its matching value on the other side. For example, since our third value here is the 28 cups of flour, it must be on the bottom on the right side since your 7 cups of flour is on the bottom of the left side. This is what the proportion should now look like:
To solve, just cross multiply and divide! 3 times 28 is 84. Then, divide the 84 by the 7 and you'll get a final answer of 12 pies!
Answer:
it can help you with answer a math problem
Step-by-step explanation:
1. Let
x = first piece
y = second piece
z = third piece
2. Arrange it into an equation
x + y + z = 50
3. The second piece is 4 times as long as the first piece so 4x = y.
The third piece is 5 times as long as the first piece so 5x = z
4. Now substitute the values
x + (4x) + (5x) = 50
5. Simplifying makes the equation into 10x = 50
6. Do the opposite of multiplying to get rid of the 10 which is dividing. Divide 50 by 10.
x = 50/10
x = 5
7. Now substitute x in 4x and 5x
4 * 5 = 20
5 * 5 = 25
8.
x = 5
y = 20
z = 25
