Question

Vinyasa bought a pizza and cut into three pieces. When he weighed the first piece he found that it was 7g lighter than the second piece and 4g .heavier than the third piece . If the whole pizza weighed 300g .how much did each the tree pieces weigh

Answer 1

Answer:

Let the weight of the 1st piece =xg

Let the weight of the 2nd piece=(x+7)g

Let the weight of the 3rd piece =(x-4)g

Total weight of pizza                 =300g

xg +x+7g+x-4g                         =300g

3x+3                                         =300g

3x                                             =300g-3

x                                               =297g/3

x                                               =99g

So, the weight of the pieces 

1st piece  = x =99g

2nd piece =x+7=99+7=106g

3rd piece =x-4 =99-4  =95g

Ans.=The weight of the three pieces of pizza are 99g, 106g and 95g.

hope this helps

Answer 2

Answer:

The weight of the three pieces of pizza are 99g, 106g and 95g

Step-by-step explanation:

Let the weight of the 1st piece =xg

Let the weight of the 2nd piece=(x+7)g

Let the weight of the 3rd piece =(x-4)g

Total weight of pizza =300g

xg +x+7g+x-4g =300g

3x+3 =300g

3x =300g-3

x =297g/3

x =99g

So, the weight of the pieces

1st piece = x =99g

2nd piece =x+7=99+7=106g

3rd piece =x-4 =99-4 =95g

Ans.=The weight of the three pieces of pizza are 99g, 106g and 95g.
