18.432 + 5.55 + 19.3
We can notice that the last number in the process of addition is 19.3 | with 1 decimal place value / 3 significant figures |
It is better to change all values to 1 decimal place value / 3 significant figures
18.432 → 18.4
5.55 → 5.6 ( 5 rounds up )
19.3 → 19.3
Let us add:
18.4 + 5.6 + 19.3 = 43.3
If you add the original numbers, you will get
18.432 + 5.55 + 19.3 = 43.282
43.282 ≈ 43.3

Answer:
x = 156/43
Step-by-step explanation:
3x + 5y = 16
8x - y = 28
3x + 5y = 16
5(8x - y = 28)
3x + 5y = 16
40x - 5y = 140
43x = 156
x = 156/43
