5x+30=7x
7x-5x=-30
2x=-30
x=-15
It is 198 inches, so it is greater.
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
one number up releases 30 times more energy than the lower number,one number down is 30 times less than the higher number.
No An atom may have less, the same, or more neutrons than protons. The number of neutrons determine which isotope of an element you have. You do expect the number of protons and electrons to be the same however. If an atom loses or gains an electron to cause the number of electrons and protons to be mismatched we call that an ion rather than an atom.
5.12 meters=512 centimetres.100cm=1mSOif you times the number of centimetres by 100...5.12x100it equals 521.Thats how you work out how many centimetres are in the number of meters.

If a number is more than 1, then three of it must be more than 3.(If I give you more than a dollar three times, you certainly wind up with more than $3.)
Expressed algebraically, this is equal to 3x + 8=y.
The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
Expressed algebraically, this is equal to 3x + 7.
3x + 2 is less than or equal to 37
2 x = 8 + 4x
19=(8xn)+3
It is: 3x = 2x+8 and the value of x is 8
No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.
