1. Is angle 2 and angle 5 are supplementary and the reason is the given
4. The answer is L || M because of the converse of the CIA theorem( corresponding interior angles)
A piece of wire is cut into two pieces. That means each part would be assigned an unknown variable. Let one part be x and the other part be y.
That means,

If the longer part is x, and the longer part is 3cm longer than the shorter part, then we would have the following;

We can now refine the equation as follow;

ANSWER:
The length of the shorter piece of wire is 6cm
Here are the answer: a) R = 3.6 and b) A = 2
Step-by-step explanation:
Given,
R is inversely proportional to A.
R ∝ 
so, R =
-------eq 1 where k is any constant
To find the values of a) R when A = 5 and
b) Value of A when R = 9
Now,
Putting R = 12 and A = 1.5 in eq 1 we get,
12 = 
or, k = 12×1.5 = 18
From eq 1 we get,
R =
--------- eq 2
Now,
a) Putting A= 5 in eq 2 we get,
R =
= 3.6
b) Putting R = 9 in eq 2 we get
R =
or, A =
= 2
1 and 18
1 × 18 = 8
1+ 18 = 19
John sold 30U
Rick sold 25U
So, Rick sold 5 fewer units than John.
Hope that helps.
