Answer:
Step-by-step explanation:
From the conditions given, the total number of the problems should be 29. This means that the sum of x and y should be 29. With this and the point-system, the best system of equation that is useful for this problem is,
x + y = 29
5x + 2y = 100
The answer is the second choice.
W <u>></u> 0.5L
Perimeter:
2L + 2W <u><</u> 180
2L + 2(0.5L) <u><</u> 180
2L + 1L <u><</u> 180
3L <u><</u> 180
<u>÷3 ÷3</u>
L <u><</u> 60
Length should be less than or equal to 60 inches while width should be greater than or equal to 30 inches.
