Mathematics

Answer:

It would be 20

Step-by-step explanation:

Step 1: Our output value is 25.

Step 2: We represent the unknown value with x

Step 3: From step 1 above 25=100%.

Step 4: Similarly, x=80%.

Step 5: This results in a pair of simple equations:

25=100%(1).

x=80%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

25/x=100%/80%

Step 7: Again, the reciprocal of both sides gives

25/x=80/100

=20

Therefore, 80% of 25% is 20

hope it helps

Let f(x)=x+2 and g(x)=2x+1 .

gogolik [260]

Step-by-step explanation:

Given g(x) = x+2 and f(x) = $2^x+1$

If f(x) = g(x)

⇔ $2^x+1$ = x+2

⇔ $2^x= x +1$

Only x= 1 and x=0 will be satisfy the above equation.

If x= 1, it gives and x=0 gives

$2^1= 1+1$ $2^0=0+1$

⇔2=2 ⇔1=1

What is the solution of √x-5 = x-11

PIT_PIT [208]

Hey!

To solve x in this equation we must first add five to both sides to get $\sqrt{x}$ on its own.

<em>Original Equation :</em>
$\sqrt{x} - 5 = x - 11$

<em>New Equation {Added 5 to Both Sides} :</em>
$\sqrt{x} =x-6$

Now we must square both sides of the equation.

<em>Old Equation :</em>
$\sqrt{x} =x-6$

<em>New Equation {Changed by Squaring Both Sides} :</em>
$x= x^{2} -12x+36$

And now we must solve the new equation.

Step 1 - Switch sides
$x^{2} -12x+36=x$

Step 2 - Subtract x from both sides
$x^{2} -12x+36-x=x-x$

Step 3 - Simplify
$x^{2} -13x+36=0$

Now we need to solve the rest of the equation using the quadratic formula.

$\frac{-(-13)+ \sqrt{(-13) ^{2}-4*1*36 } }{2*1}$

${13+ \sqrt{(-13)^{2}-4*1*36 }=13+ \sqrt{25}$

$\frac{13+ \sqrt{25}}{2}$

$\sqrt{25}=5$

$\frac{13+5}{2}$

$\frac{18}{2}$

9

$\frac{-(-13)- \sqrt{(-13) ^{2} -4*1*36} }{2*1}$

4

<em>So, this means that in the equation $\sqrt{x} -5=x-11$ ,</em> x = 9 <em>and </em>x = 4.

Hope this helps!
