Solve for x. 45(15x+20)−7x=56(12x−24)+6

Nady [450]

Answer:

The value of the equation for x is $x=\frac{1119}{2}$ or 559.5.

Step-by-step explanation:

Consider the provided equation.

$45(15x+20)-7x=56(12x-24)+6$

We need to solve the equation for x.

Use the distributive property: $a(b+c)=ab+ac$

$45(15x+20)-7x=56(12x-24)+6$

$675x+900-7x=672x-1344+6$

Add the like terms.

$668x+900=672x-1338$

Isolate the variable as shown:

$672x-668x=900+1338$

$4x=2238$

$x=\frac{2238}{4}$

$x=\frac{1119}{2}$

Hence, the value of the equation for x is $x=\frac{1119}{2}$ or 559.5.

Answer: 4

<u>Explanation:</u>

f(x) = 2x - 1

f(√2) = 2√2 - 1

f(1) = 2(1) - 1

= 2 - 1

= 1

f(√3) = 2√3 - 1

*******************************************************

$\frac{f(\sqrt{2})-f(1)}{\sqrt{2}-1} +\frac{f(\sqrt{3})-f(\sqrt{2})}{\sqrt{3}-\sqrt{2}}$

= $\frac{(2\sqrt{2}-1)-1}{\sqrt{2}-1} +\frac{(2\sqrt{3}-1)-(2\sqrt{2}-1)}{\sqrt{3}-\sqrt{2}}$

= $\frac{2\sqrt{2}-2}{\sqrt{2}-1} +\frac{2\sqrt{3}-2\sqrt{2}}{\sqrt{3}-\sqrt{2}}$

= $\frac{2\sqrt{2}-2}{\sqrt{2}-1}(\frac{\sqrt{2}+1}{\sqrt{2}+1})+\frac{2\sqrt{3}-2\sqrt{2}}{\sqrt{3}-\sqrt{2}}(\frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}+\sqrt{2}})$

= $\frac{4+2\sqrt{2}-2\sqrt{2}-2}{2 - 1} + \frac{6 +2\sqrt{6}-2\sqrt{6}-4}{3-2}$

= $\frac{2}{1} +\frac{2}{1}$

= 4
