It takes 22 pounds of seed to completely plant a 4-acre field. how many pounds of seed are needed per acre?

5.5 pounds of seeds

Step-by-step explanation:

22 pounds seeds = 4-acre field

(x) pounds seeds = 1-acre(per acre)

x= 22/4

 = 5.5 pounds of seeds

x=18, m∠1=140, m∠2=40

Step-by-step explanation:

m∠1 and m∠2 will equal up to 180

7x+14+2x+4=180

Combine like-terms

9x+18=180

Subtract 18 from both sides.

9x=162

Divide both sides by 9

x=18

Then plug in 18 for x in the angle measures

7(18)+14=140

2(18)+4=40
