X = train cars, y = tracks
0.4x + 0.2y = 5.2.....this one deals with the constructing
0.6x + 0.1y = 4.2 ....this one deals with the painting
Since they both have 3x terms subtract the second from the first to get rid of the x terms...
3x+2y=10
-3x+y=-13
__________
3y=-3
y=-1, which makes 3x+2y=10 become: 3x-2=10 so
x=4
So the solution is the point (4, -1)
90 degrees is 1/4 of the circle ( 90 * 4 = 360 degrees = full circle).
Divide the area of the circle by 4:
314 / 4 = 78.5 square inches is shaded.
Answer:
Thousands place
Step-by-step explanation:
HTH = Hundred Thousands
THT = Ten Thousands
TH = Thousands
H = Hundreds
T = Tens
O = Ones
| HTH | THT | TH | H | T | O |
| 1 | 0 | 6 | 5 | 3 | 4 |
