Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
I think that it is 15 minutes
Answer:
Structure of the Atom. The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
*Simply the atomic number helps the structure of the atom because the number of protons it's equal to the atomic number.*
Solving for x
-15x+20y=60
-15x=60-2y
x= (-4+4/3)
x=(-8/3) Answer
