The shape of the field is rectangle
The perimeter of a rectangle is the total length of all four borders.
x + x + y + y = 1040/3 ⇒ Collecting like term
2x + 2y = 1040/3 ⇒ We want to isolate 'y', so move '2x' to the right hand side of equation
2y = 1040/3 ÷ 2x
y =

÷ 2
y = 1040/12x
Answer:
it is a triangle whose sides appear to be all different lengths
Joy walked 1/3 units (miles? kilometers? it doesn't matter actually) in 3 of the 5 days. So, walking 1/3 units for three days tallies up to

If we add the day when she walked 1/2 units and the day she walked 2/3 units, we get

The solution to the absolute-value inequality is x > 9; and x < -1
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the nonequal comparison of two or more numbers and variables.
Let x represent the unknown number, hence:
|x - 4| > 5
(x - 4) > 5; and -(x - 4) > 5
x > 9; and x < -1
The solution to the absolute-value inequality is x > 9; and x < -1
