Without a ratio, we cannot answer these questions. However, if we had a ratio such as 2 cups flour to 3 eggs, we could use cross-multiplication to find the amount of flour needed for 6 eggs (12 cups) and the amount of eggs needed for 15 cups of flour (45 eggs).
To answer these questions, we need a ratio between flour and eggs. However, without this ratio, it's impossible to answer questions a and b correctly. Usually in cooking, the amounts of ingredients used can vary depending on the recipe.

Fill in the blank question.
REASONING The figure shows a straight portion of the course for a city marathon. The water station W is located at the midpoint of AB .
a. What is the length of the course from point A to point W?
Part B
Select the correct choices to complete the sentence.
b. Write a paragraph proof for your answer to part a.
The length of the course from point A to point W can be found using the midpoint formula. To write a paragraph proof, mention the given information and use the midpoint formula to calculate the length.
Part A:
To find the length of the course from point A to point W, we need to determine the distance between these two points. Since W is the midpoint of segment AB, we can use the midpoint formula to find the coordinates of W. If the coordinates of A are (x1, y1) and the coordinates of B are (x2, y2), the coordinates of W would be the averages of x1 and x2, and y1 and y2.
Part B:
To write a paragraph proof for Part A, we can state the given information and use the midpoint formula to show how we calculated the length of the course from point A to point W. We can mention the formula for the midpoint and use the given information to substitute the values, then simplify the expression to find the length.

B. y = 2x + 1
C. y = 5x - 1
D. y = -5x + 1
The value of the function f(x)=3(4-x) when x=7 is -9. This is calculated by substituting x=7 into the function and simplifying.
To find the value of the function f(x)=3(4-x) when x=7, you should insert x's value into the equation. Therefore, the function takes the form: f(7)=3(4-7). Then you simplify it to: f(7)=3(-3) and further simplification gives: f(7)=-9.
