To solve this problem, we need to set up a proportion.
2 batches of nut bars/ 4 eggs = 1 batch of nut bars / x eggs.
To solve this proportion, we use cross products, or multiplying the numerator of one number by the denominator of the other and setting them equal to one another.
(4 eggs) (1 batch) = (2 batches) (x eggs)
4= 2x
2=x
Therefore, 2 eggs are used in each batch of nut bars.
Step-by-step explanation:
Firstly, there's a typing error at (x=1)². I assume it is (x-1)². If my assumption is correct,then:
x²-2x+1-4x=x²-2x+1
x²-6x+1-x²+2x-1=0
-4x=0
x=0
