-4x -7 - 3x + 4 = 25

-4x-3x-7+4= 25 rearranging

-7x-3= 25

Move -3 to the other side. Sign changes from -3 to +3.

-7x-3+3=25+3

-7x= 28

divide by -7

-7x/-7= 28/-7

x= -4

Answer: x= -4

adam is going to cook a turkey for 14 people he want 3/4lb of turkey per person 1lb =450g how much would a turkey in kg would I
klemol [59]
In this question, let us first note down all the important information's that have been provided in the question.
The number of people that Adam is cooking for = 14
Amount of turkey required per person = 3/4 pounds
Now
Total amount of turkey required by Adam to cook for 14 people = (3/4) * 14
                                                                                                     = 21/2
So 21/2 pound of turkey is required by Adam to cook for 14 people. This weight of turkey has to be converted to gram first and then to kilogram.
We already know
1 lb = 450 g
Then
21/2 lb = 450 * (21/2) gram
            = 225 * 21
            = 4721 gram
Now again we know
1000 g = 1 kg
4721 gm = (4721/1000) kg
               = 4.721 kg
So Adam needs to have a turkey weighing 4.721 gram to cook for the 14 people. I hope the procedure is clear to you.
