<span>4x - 6 = x + 3

Subtract x from each side
</span><span><span><span><span>4x</span>−6</span>−x</span>=<span><span>x+3</span>−<span>x
<span><span><span>3x</span>−6</span>=<span>3
</span></span>
Add 6 to each side
<span><span><span><span>3x</span>−6</span>+6</span>=<span>3+<span>6
<span><span>3x</span>=<span>9

Divide each side by 3
3x ÷ 3 = 9 ÷ 3
x = 3
============================================================
Checking work....

Substitute 3 for x in the equation and solve
<span>4(3)- 6 = (3) + 3
12 - 6 = 3 + 3
6 = 6
This is true, so 3 is x</span></span></span></span></span></span></span></span></span>

Plssss help what is x
makvit [3.9K]

Answer:

x = 4

Step-by-step explanation:

If you do not want to read the explanation go the the next part in bold

Ok so the shorter leg of the triangle is a radius of the circle. ( This is indicated by the point in the middle of the circle.) for the hypotenuse we are given one part of the length (2) The other part also happens to be a radius ( remember that a radius is a line that starts from the center of the triangle to any point of the circumference. ) Also remember that the radius is equal to 3. That being said the hypotenuse = 2+3 which equals 5.  

This triangle then happens to be a right triangle. ( A triangle formed by a tangent line and a radius is a right triangle.) This means that we can use the Pythagorean theorem to solve for x.

Below here is where the work is shown

a² + b² = c². where a and b = legs and c = hypotenuse. We are given the hypotenuse (5) and a leg (3) So we plug in what we are given and solve for the missing information. 5² = 3² + b²  

5² = 25

3² = 9

we would then have 25 = 9 + b²

Next we subtract 9 from each side

25 - 9 = 16

9 - 9 cancels out

Now we have 16 = b²

finally we want to get rid of the ²

To do so we take the square root of each side

\sqrt{16}=4\\\sqrt{b^2}=b\\b = 4

we're left with b = 4 which means that x = 4

Convert 221 quinary number into decimal number.​
aleksley [76]

Step-by-step explanation:

<h2>______________________</h2>

( First of all to convert quinary to decimal we need to multiply them by 5 )

So let's solve now.....

= 221

Solution,

Converting quinary number to decimal .....

= 2 × 5² + 2 × 5¹ + 1 × 5⁰

The value of any number to the power 0 is 1 ...

= 2 × 25 + 2 × 5 + 1 × 1

= 50 + 10 + 1

= 61..

<h2>______________________</h2>

Hence the answer is 61....
