an has pounds of pistachios. He needs 27of the pistachios to make trail mix. What fraction of a pound of pistachios will Ian use for the trail mix

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

24
