Answers
Answer 2 : The term that describes elements with different atomic masses due to varying numbers of neutrons is "isotopes". Isotope elements have same number of protons but different number of neutrons.
Answer 3 : As stated in the answer 1, atomic mass of an atoms is the sum of all protons and neutrons in it's nucleus. So, this carbon isotope has 6 protons and 7 neutrons in its nucleus so : 7+6=13 . It's atomic mass is 13 atomic mass unit.(amu)
Answer:
1. the sum of all protons and neutrons in the atomic nucleus
2. isotopes
3. 13 amu

the answer is a numberical expression or a closed phrase
open phrase=numbers operations and placeholders exg 3+x
closed phrase=numbers operations no placeholder exg 3+4
open sentence=numbers operations placeholder and relation symbol (=><) exg 3+x=8
closed senctance=number operations no placeholder and relation symbol exg
3+4=9
so it's a closed phrase

45 / 150 = 0.3
To find a percentage based off of a decimal, you simply have to multiply the decimal by 100, or (my personal shortcut) just shift the decimal point over two places to the left.
0.3 = 30%
45 is 30% of 150.
Hope that helped! =)
x%=x/100
'is' means euqals
'of' means multiply
45 is what percetn ot 150 means
45=x/100 times 150
45=150x/100
45=15x/10
45=3x/2
45=3/2x
multiply both sides by 2/3 to make one (3/2 times 2/3=6/6=1 and x times 1=x)
90/3=6/6x
30=x
answer is 30%

4/5x>14
Answers
Well, first, you need to know what you want to 'do' to it.
You want to find the description of what 'x' has to be in order to
make that inequality a true statement. Here's one way to do it:
4/5 x > 14
Multiply each side by 5 : 4 x > 70
Divide each side by 4 : x > 17.5 .
That's it. As long as 'x' is more than 17.5 ,
the original inequality is true.
