<h2>
<u>RECIPROCAL</u></h2>
<h3>ANSWER: </h3>
<h3>EXPLANATION:</h3>
As we can see above, it's clear that 3 and 1/3 are reciprocals of each other.
And we can find the reciprocal of 1/3 by forming a fraction and to multiply the numerator and denominator by 3.
Hence, 3/1 or 3 is the correct answer.

Answer:
Step-by-step explanation:
An expression is a mathematical statement that does not contain an equal sign. It cannot be solved for unless the value of the variable is given. An equation is a mathematical statement or sentence comprised of two equalities or expressions joined with an equal sign.
Answer: C) No solution
Let’s solve this. First we need to put the first equation into y=mx+b form. Let’s do this now.
First equation-
2•4y=10
*subtract 2*
4y=8
*divide 4*
y=2
Now that we know the value of y, let’s substitute that into the second equation.
2•4y= -10
2•4(2)= -10
2•8= -10
16= -10
When solved, these equations produce a result where both sides do not equal each other. 16 does not equal -10, making this have no solution.

Unlike terms I guess meaning a zero pair?
The question is asking how many combinations of two people can be made from a group of ten people.
Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.
A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
