Answer:
Substitute in the values of both given coordinates & form 2 equations:
Find the value of B from the equation 2A - B = 1:
Substitute in the B-value to the other equation:
Find the B-value using the equation from before:
Therefore the equation Ax + By = 1 would equal:
1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields
Part 2:
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:
since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is 18 cutouts
2 2/5 feet=12/5 feet.
