Answer: ×=1.29
Step-by-step explanation:
Open the brackets
-12x +9 +5x
-12x+5x=-9
-7x= -9
Divide both sides by -7
X=9/7 =1.29
Answer: See below
Step-by-step explanation:
This relates to the usage of water displacement.
- Have the 10 ml of water ready in a measuring flask (or any container that has a scale)
- Put the marble into the water
- Observe how much did the water rise
- Subtract the current water level by the original 10 ml
- The final answer would be the volume.

EXTRA (Only for advanced purposes, if you do not understand, it is totally fine)
Refer to the attachment below to finish the question.
Assuming the water levels are integer,
- The original water level is <u>13.33 ml</u>
- After the rock is put in, the water level is raised to <u>30 ml</u>
Then, we do the fourth step which is subtraction
Hope this helps!! :)

Answer:
31.4
Step-by-step explanation:
C = 2πr OR C = πd
But, we need to find r first.
![A = \pi r^2\\25\pi = \pi r^2\\\sqrt{25} = \sqrt{r^2} \\r=5\\\\C=2\pi r\\C=2\pi (5)\\C= 10\pi \\C= 31.4](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2%5C%5C25%5Cpi%20%3D%20%5Cpi%20r%5E2%5C%5C%5Csqrt%7B25%7D%20%3D%20%5Csqrt%7Br%5E2%7D%20%5C%5Cr%3D5%5C%5C%5C%5CC%3D2%5Cpi%20r%5C%5CC%3D2%5Cpi%20%285%29%5C%5CC%3D%2010%5Cpi%20%5C%5CC%3D%2031.4)
