<u>Answer:</u>
Ordered pair = (3, 2)
<u>Step-by-step explanation:</u>
We are given the following equations and we are to solve them by substitution method:
--- (1)
--- (2)
Substituting the value of y from equation (2) to (1):



x = 3
Substituting this value of x in equation (2):

y = 2
So the ordered pair is (3, 2).
A.450.80
Multiply 40x9.80=392
Take 1/2 of 9.80 that equal 4.90
4.90 plus 9.80 $14.70x4=58.80
$58.80 plus 392 equals 450.80
The ordered pair is a solution of x - y = 2 and 3y - x = 8 is (x, y) = (7, 5)
<h3><u>Solution:</u></h3>
Given two equations are:
x - y = 2 and 3y - x = 8
<em><u>To find: orderes pair i.e (x, y)</u></em>
Let us consider:
x - y = 2 ------- eqn 1
3y - x = 8 --------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to find values of "x" and "y"</u></em>
On rearranging eqn 2, we get
-x + 3y = 8 ------ eqn 3
Add eqn 1 and eqn 3
x - y = 2
-x + 3y = 8
(+) ---------------
0 + 2y = 10
2y = 10
<h3>y = 5</h3>
Therefore from eqn 1,
x - y = 2
x - 5 = 2
x = 5 + 2 = 7
<h3>x = 7</h3>
Thus the ordered pair to the given equations are (x, y) = (7, 5)
Answer: 27 meters
Step-by-step explanation:
2 sides are 14 m so 14×2=28
now take the total... 82-28=54
no divide the rest by 2 since there are 2 sides left... 54÷2=27
The area of any rectangle is the product of its length and its width -

. We've been given the area and the length, and we can use those values to solve for the width:

So, the length of the missing side is
9 ft.
