The answer is B. They did not multiply the constant 2 by 4 when multiplying through to remove the fraction. so the correct answer would be x-4y=-8
X=212, y=88, n=50, L=212 hope this helps
Y=8x+40
8 is slope because she adds 8$ weekly and 40 is what she started with
Answer: $210.75
Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75
Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75
