Answer:
x = 19
Step-by-step explanation:
To find the value of x, you set the equations as equal to each other:
![x+23 = 2x+4](https://tex.z-dn.net/?f=x%2B23%20%3D%202x%2B4)
Then you simplify:
![23 = 2x + 4 - x\\23 = x + 4\\23-4 = x\\19=x](https://tex.z-dn.net/?f=23%20%3D%202x%20%2B%204%20-%20x%5C%5C23%20%3D%20x%20%2B%204%5C%5C23-4%20%3D%20x%5C%5C19%3Dx)
The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
<h3>What is the area of the circle?</h3>
The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,
![A=\pi\dfrac{d^2}{4}](https://tex.z-dn.net/?f=A%3D%5Cpi%5Cdfrac%7Bd%5E2%7D%7B4%7D)
Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.
![d=6](https://tex.z-dn.net/?f=d%3D6)
Put this value in the above formula to find the area of the circle as,
![A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm](https://tex.z-dn.net/?f=A%3D%5Cpi%5Cdfrac%7B6%5E2%7D%7B4%7D%5C%5CA%3D%5Cpi%5Cdfrac%7B36%7D%7B4%7D%5C%5CA%3D%5Cpi%5Ctimes9%5C%5CA%3D9%5Cpi%5Crm%5C%3B%20cm)
Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

Yes, because if you divide 4 and 3 by 2, you get 2 and 1.5
Q1 :
x + (x+25) = 131
2x + 25 = 131
2x = 131-25
2x = 106
x = 53
53+25 = 78
Therefore, 53+78=131
Q2 :
x + (x+14) = 58
2x + 14 = 58
2x = 58-14
2x = 44
x = 22
22+14 = 36
Therefore, 22+36=58
Q3 :
let ‘b’ be basketball
b + (3+b) = 27
2b + 3 = 27
2b = 27-3
2b = 24
b = 12
12 + 3 = 15
Therefore, 12 + 15 = 27
12 basketballs and 15 footballs were sold on Saturday
Q4 :
let ‘s’ be soup
s + 2s = 738
3s = 738
s = 246
246 x 2 = 492
Therefore, the hamburger has 492 calories while the soup as 246 calories
