Answer:
x = 23
Step-by-step explanation:
6x+19+x = 180
7x = 180 - 19
7x = 161
x = 161/7
x = 23
It is 546.4583333333333, which would simplify to 546.46 if to the hundredths place or 546.5 to the tens place

Answer:
The length of the rectangular field is 12 ft and the width is 5 ft.
Step-by-step explanation:
The area of a rectangle is:

The area of a rectangular field is, <em>A</em> = 60 ft.
The length of the field is:
l = w + 7
Compute the width of the field as follows:


Factorize the last equation by splitting the middle term as follows:

Now, since the width of rectangular field cannot be negative, the width is 5 ft.
Compute the length as follows:
l = w + 7
= 5 + 7
= 12
The length of the rectangular field is 12 ft.
