How do you factor 18r^5p^3-12r^3p^5+30rp^4

1 answer:

3 0

6rp^3 is the greatest common factor. Take that out and see what's left.

= 6rp^3*(3r^4 -2r^2p^2 +5p) . . . . . factors no further

5/4 to 3/8 as a percent change

Digiron [165]

Well, what's the diffrence from 5/4 to 3/8?

$\bf \cfrac{5}{4}-\cfrac{3}{8}\qquad \stackrel{\textit{LCD is 8 clearly}}{\implies }\qquad \cfrac{10-3}{8}\implies \cfrac{7}{8}$

so, if we take 5/4 to be the 100%, what is 7/8 off of it in percentage anyway?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{5}{4}&100\\\\
\frac{7}{8}&x
\end{array}\implies \cfrac{\quad \frac{5}{4}\quad }{\frac{7}{8}}=\cfrac{100}{x}\implies \cfrac{5}{4}\cdot \cfrac{8}{7}=\cfrac{100}{x}
\\\\\\
\cfrac{40}{28}=\cfrac{100}{x}\implies x=\cfrac{28\cdot 100}{40}$

The sum of eight and a number is one hundred. What is the number?

KonstantinChe [14]

Salutations!

Let the number be $x$

Your equation would be $x+8=100$

Now that we have our equation, lets solve this!

Solve this by keeping the variables aside, and the numbers aside

$x=100 -8$

The sign would change because your are isolating the number

$x=100-8$

$x= 92$

Hope I helped (:

Have a great day!

Solve by the substitution method.

GalinKa [24]

Answer:

The unique solution to the system is (x,y){(-9,-3)}

Step-by-step explanation:

x - y = -6 equation 1

5x + 6y = -63 equation 2

We will find the value of x from equation 1.

x= y-6

Now put the value of x in equation 2.

5(y-6)+6y = -63

5y-30+6y = -63

Combine the like terms:

5y+6y= -63+30

11y = -33

Divide both sides by 11.

11y/11 = -33/11

y = -3

Now put the value y = -3 in x=y-6

x = y-6

x= -3-6

x= -9

Therefore The unique solution to the system is (x,y){(-9,-3)} ....
