What is the average amount of salt called for in each recipe?

The answer is 3.5

To find the average of a set of numbers, add them together then divide the result by how many numbers there were.

To find the average of 4, 4, 4, and 2, add them: 4+4+4+2=14. There were 4 numbers. Divide 14 by 4: the answer is 3.5

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
