Is 9 a solution to the equation 21=3p-5? Show work

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

21 = 3p - 5

Step 1 : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

Step 2 : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.

Write a subtraction fact with the same difference as 16-7?

Alona [7]

So, this is asking for any number that subtracts to = 16-7

Well, 16-7= 9 so use any two numbers that would subtract to equal 9

Like so:

11-2=9
18-9=9
34-25=9
-2-11=9
Etc....

Hope this helps! :)

Dividing rational expressions

Galina-37 [17]

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-----------------------------\\\\
\cfrac{x+3}{x^2-2x}\cdot \cfrac{(x-2)^2}{x^2-9}\implies \cfrac{x+3}{x^2-2x}\cdot \cfrac{(x-2)(x-2)}{x^2-3^2}
\\\\\\
\cfrac{x+3}{x(x-2)}\cdot \cfrac{(x-2)(x-2)}{x^2-3^2}\implies \cfrac{\underline{x+3}}{x\underline{(x-2)}}\cdot \cfrac{\underline{(x-2)}(x-2)}{(x-3)\underline{(x+3)}}
\\\\\\
\cfrac{x-2}{x(x-3)}\iff\cfrac{x-2}{x^2-3x}$
