A rectangle has two couples of equal sides, so a soccer fields has two 80-meters sides and two 120-meters sides.
This leads to a perimeter of

If you go around it twice, you'll run 800 meters
Standard form is written Ax + By = C where A, B, and C are all integers.
In other words, no fractions.
Also, the A or the coefficient of the x term must be positive.
The only thing we need to do is add 7x to both sides to get 7x + y = -1.
So 7x + y = -1 is our answer.
Answer:
x=10
Step-by-step explanation:
multiply 5 on both sides to cancel out the 5 and your left with x=10
<span>The reciprocal of a fraction is simply the reverse
position of the original fraction, its numerator and denominator. It is
represented by the formula of 1/number (fraction). To get the reciprocal of the
number, divide one by the fractional number. You are given the number 6/5. So you
have a numerator of 6 and a denominator of five. Simply swap them and you get
the new numerator as 5 and the new denominator as 6. Or you can just divide
1/(6/5) then you will get 5/6. The answer is letter D.</span>
