Lets x is the labor charges per hour
3x + 126.53 = 220.28
3x = 220.28 - 126.53
3x = 93.75
x = 93.75 / 3
x = 31.25
answer: $31.25 per hour charged for labor
y-intercept is -3 so it must pass the vertical line -3.
Now start from point (0,-3) and rise up by 3, then go right by 1 since the slope is 3/1 or 3.
It should look like this:
19. Perimeter of rectangle = 2(l + b)
l = 25m
b = 16m
Perimeter of rectangular park = 2 (25 + 16)
= 50 + 32
= 82m
Perimeter of square park = 82m
(given that, perimeter of rectangular and square park are equal)
Perimeter of square = 4a
4a = 82
a = 82/4
a = 20.5m
Area of square park = a²
= 20.5²
= 420.25m²
20. Perimeter of regular hexagon = 6a
a = 2.5
6a = 6 × 2.5
= 15cm
21. Perimeter of regular decagon = 10a
a = 8
10a = 10 × 8
= 80cm
Well,you have the answer on your paper already...
