Answer:
sorry men this is not the answer
Step-by-step explanation
All will apply except for (A, C, and E) because those lengths are less than 4/6. So (B, D and F) are the correct answers.
That’s would be 12 times 4 2/3 so the answer is 56 seconds
100y+x=230
150y+x=320
Y being the price per kilogram of steel bar, x being the added delivery fee.
If you were to solve the equaltion it would go x=230-100y by changing the first equation around the replacing that for the x int he second group, so you would get 150y+230-100y=320 or 50y=90 So Y=9/5dollars per kilogram. Or $1.8per kilogram, the delivery fee being $50
Hope this will help you if I am answering this right.
