Solve for x please for 10 points

Ira Lisetskai [31]

Answer:

$\frac{x-2}{2+1}=\frac{4x-5}{3}$

$\frac{x-2}{3} =\frac{4x-5}{3}$

$3*\frac{x-2}{3} =\frac{4x-5}{3}*3$

$x-2=4x-5$

$x-2+5=4x-5+5$

$x-x+3=4x-x$

$3=3x$

$\frac{3}{3} =\frac{3x}{3}$

$1=x$

Anton [14]

Answer:

See below.

Step-by-step explanation:

Let x = amount of money you have in your account.

The money in your account plus the $125 extra that you need equals the total cost of the computer.

The equation is:

x + 125 = 2250

Now we solve the equation by subtracting 125 from both sides.

x = 2125

Answer: You have now $2125 in your account

Trigonometric equations<br><br> 5sinx = 3sinx + square root of 2

Lera25 [3.4K]

$\qquad\qquad\huge\underline{{\sf Answer}}♪$

Let's solve for x ~

$\qquad \sf \dashrightarrow \:5 \sin(x) = 3 \sin(x) + \sqrt{2}$

$\qquad \sf \dashrightarrow \:5 \sin(x) - 3 \sin(x) = \sqrt{2}$

$\qquad \sf \dashrightarrow \:2 \sin(x) = \sqrt{2}$

$\qquad \sf \dashrightarrow \: \sin(x) = \sqrt{2} \div 2$

$\qquad \sf \dashrightarrow \: \sin(x) = \frac{1}{ \sqrt{2} }$

$\qquad \sf \dashrightarrow \:x = 45 \degree \: \: or \: \: \frac{\pi}{4} \: rad$

Describe how the graph of y= x – 12 is like the graph of y= x and how it is different

puteri [66]

The two graphs have the same slope. But the graph of <span>y= x – 12 is 12 units below the graph of y = x. We call that a "vertical translation."
