3. the perimeter of a rectangular playing field is 504 yards. the area of the
playing field is 14,276 square yards. write a system of equations that could
be used to find the values of i, the length of the field, and w, the width of the
field, that will satisfy these conditions.
4=

The perimeter is twice the sum of the length and the width:

The area is the product of the dimensions:

So, the system is

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
