Answer:
99g, 106g, 95g
Step-by-step explanation:
Let the 1st slice pizza weighs x g
2nd slice pizza weighs x +7 g
3rd slice pizza weighs x- 4 g
Total, x + x + 7 + x -4 = 300g (given)
By solving, 3x + 3 = 300
3x = 297
x = 297/3 = 99 g
Hence, 1st slice pizza = x g = 99g
2nd slice pizza = x + 7 g = 106g
3rd slice pizza = x - 4 g = 95g
hope this will help you.
Answer:
hope it helps.. :)
Step-by-step explanation:
if all the three pieces weighed 300g, this is obvious that:
1st piece + 2nd piece + 3rd piece = the whole weight of pizza
x + (x+7) + (x-4) = 300
x + x + 7 + x -4 = 300
3x + 3 = 300
3x = 300 - 3
3x = 297
x = 99
putting the value of "x" in all expressions
1st piece weighed = x
= 99g
2nd piece weighed = x+7
= 99 + 7
= 106g
3rd piece weighed = x-4
= 99 - 4
= 95g
lets see if the answer is correct or not (optional)
99g + 106g + 95g = 300g
300g = 300g
hence proved.. :)
