Answer:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

And replacing into equation (1) we got:



Adding 14 in both sides we got:

And dividing 10 on both sides we got:

And then we can solve for X and we got:

Step-by-step explanation:
For this case we can set up the following notation:
X represent the lenght
Y represent the width
And since we have a rectangular playing filed the perimeter is given by:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

And replacing into equation (1) we got:



Adding 14 in both sides we got:

And dividing 10 on both sides we got:

And then we can solve for X and we got:

Answer:
1
Step-by-step explanation:
Equation= |4| - |-3|=?
absolute value of 4 is 4. absolute value of -3 is 3.
So, 4-3=1, thus 1 is the answer
Answer:
$27.30
Step-by-step explanation:
$4.80×5=$24.00+$3.30=$27.30
So..
3x+6=2(x-3) distribute
3x+6=2x-6 combine like terms
x=-12 solution
