Answer:
Nemo: 10
De'Shaun: 5
Adela: 20
Jefferson: 15
Step-by-step explanation:
Let Nemo's age be x
De'Shaun's age= x-5
Adela's age= 2x
Jefferson's age= 3(x-5)
= 3x-15
x+x-5+2x+3x-15= 50
7x-20= 50
7x= 50+20
7x= 70
x= 10
Nemo's age= 10
De'Shaun's age= 10-5
= 5
Adela's age= 2(10)
= 20
Jefferson's age= 3(10)-15
= 30-15
= 15
Answer:
Age of Nemo = 10 years
De'shaun's age = 5 years
Adela's age = 20 years
Jefferson's age = 15 years
Step-by-step explanation:
Age of Nemo = x years
So, De'shaun's age = x - 5
Adela's age = 2*x = 2x
Jefferson's age = 3* (x -5) = 3*x - 3*5 = 3x -15
Total age = 50
x + x - 5 + 2x + 3x - 15 = 50 {Combine like terms}
x + x + 2x + 3x - 5 - 15 = 50
7x - 20 = 50
7x = 50 + 20
7x = 70
x = 70/7 = 10
Age of Nemo = 10 years
De'shaun's age = 10 - 5 = 5 years
Adela's age = 2* 10 = 20 years
Jefferson's age = 3*10 -15 = 30 - 15 = 15 years
