Let's do this step by step:
Subtract both sides by 7
-2|x-4|= -10
Divide each side by -2
|x-4|= 5
Now since this is an absolute value equation, you will have two answers. This means you make the equation both positive and negative.
X-4= 5and -(x-4)= 5
Solve for x for both
X-4= 5: add four on both sides
X= 9
-x+ 4= 5: subtract 4 and divide by -1
X= -1
So your answer is: X= -1 , 9
The area A of a circle is equal to: pi times the radius squared
A = πr²
A = π5², which is 78.5
Answer:12/1
Step-by-step explanation:
7.
Convert 41% into a decimal:
![41 \div 100 = 0.41](https://tex.z-dn.net/?f=41%20%5Cdiv%20100%20%3D%200.41)
Multiply 48 by this decimal:
![0.41 * 48 = 19.7](https://tex.z-dn.net/?f=0.41%20%2A%2048%20%3D%2019.7)
The answer is
19.7.

Convert 35% into a decimal:
![35 \div 100 = 0.35](https://tex.z-dn.net/?f=35%20%5Cdiv%20100%20%3D%200.35)
Multiply 22 by this decimal:
![0.35 * 22 = 7.7](https://tex.z-dn.net/?f=0.35%20%2A%2022%20%3D%207.7)
The answer is
7.7.
