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
Answer:
intersection of the y axis
You can use repeated subtraction to solve 84 divided by 6 by subtracting 6 from 84 repeatedly, and stopping until either you reach zero, or until you cannot make any more groups of 6.
Answer:
18
Step-by-step explanation:
First design: upholstery and wood
Second design: upholstery
For the first design the possible chairs we can make are 6 with the first type of wood and 6 with the second one. Therefore we sum both results=12.
For the second the possible chairs we can make are 6.
The total of possibles chairs we can make are 6 + 12 = 18.
