85p per (1/2) kg.
1 kg = 1000g, (1/2)kg = (1/2) * 1000 = 500 g
It means:
500g cost 85p
1g would cost 85p/500
100g would then cost (85p/500) * 100 = 19p
Cost of 100g is = 19p
Hope this explains it.
Answer:
The answer is option 3.
Step-by-step explanation:
Option 3 is correct because it has parentheses around 40 - x, but not the cube itself or the 3rd power if you didn't know what I meant. Anyway, the reason this is correct is because if you look at any order of operations, you will notice that parentheses always comes before powered numbers, so if you were to choose, say option 2, it would be a completely different answer than option 3, not to mention wrong also.
Z° + 43° = 180°-------(linear angles)
z° = 180 - 43°
z = 137°
