The solution of x+b> -14 is x> -21. what is the value of b?

  b = 7

Step-by-step explanation:

You can start with either inequality, then add the required amount to make it look like the other one.

___

Starting with x > -21

  x > -21

  x + 7 > -14 . . . . . add 7 to both sides

  b = 7 . . . . . . . . .  compare to the form x + b > -14

___

Starting with x + b > -14

  x + b > -14

  x + b -7 > -21 . . . add -7 to both sides

  b -7 = 0 . . . . . . compare to the form x > -21. 0 is added to x.

  b = 7 . . . . . . . . add 7 to both sides

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

answer: 12   they all have at least 28 days
