Answer:
(2, 0)
Step-by-step explanation:
The only table entry with y = 0 is (x, y) = (2, 0). That is the x-intercept.
In a given radioactive nuclide, we can easily find the mass number, mass of proton and neutron by subtracting the mass of proton from the mass number. The mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.
<h3>Properties of an atom</h3>
Data;
- Mass Number = 131
- Atomic Number = 56
In a given atom, the mass number of an atom comprises of the mass of proton and mass of neutron. The atomic number of the element or atom is equal to the mass of the proton.
In this case,
mass number = mass of proton + mass of neutron.
From the calculation above, the mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.

Answer:
Step-by-step explanation:
1/3(x+6)=12
x+6=12/(1/3)
x+6=(12/1)(3/1)
x+6=36/1
x+6=36
x=36-6
x=30
Answer: 30
--------------------
12(x+1/6)=8
x+1/6=8/12
x=8/12-1/6
x=8/12-2/12
x=6/12
simplify
x=1/2
Answer: 1/2
------------------
-3(x+2)=-18
x+2=-18/-3
x+2=6
x=6-2
x=4
Answer: 4
-----------------
-3(x-2)=21
x-2=21/-3
x-2=-7
x=-7+2
x=-5
Answer: -5
-------------------
-5(4-x)=-40
4-x=-40/-5
4-x=8
x=4-8
x=-4
Answer: -4
------------------
1/4(6-x)=1/4
6-x=(1/4)/(1/4)
6-x=1
x=6-1
x=5
Answer: 5
<em>*It's debatable that there are 2 answers to this question because of how it's worded*</em>
For the first answer:
There would be 66 books left.
To get this, you need to multiply the original amount (120) by the decimal form of the percentage.
So, to get the decimal form you need to divide by 100, which essentially means you move the decimal 2 places to the left.
55% then becomes .55
So, 120 * .55 = 66
For the second answer:
If the question means that you need to decrease 120 by 55% <em>of 120 </em>then the answer would be 54.
120 - 66 = 54
So, depending on the answer choices and how it's interpreted, do what you will with this information.
