3x - 6 = 2(x + 4). find the value

1 answer:

6 0

3x -6 = 2(x + 4)
Multiply x by two and 4 by 2 to get
3x - 6 = 2x + 8
You want the x to be alone on one side so you add six on both sides to get rid of it to get:
3x = 2x + 14
You still don’t have just one x and it isn’t alone on one side, so you subtract 2x from both sides and get
x = 14

Locate root 9.8 on number line

Answer: See attached

Step-by-step explanation:

"Root 9.8" means the square root of 9.8, $\sqrt{9.8}$ .

Since we are being asked to find it on the number line, I am guessing they want us to estimate. We know that the square root of 9, $\sqrt{9}$ , is equal to 3. Since 9.8 is slightly bigger than 9, the square root of 9.8 will be a little bit over 3.
