of James and Dan. How old is each person
1 answer:
Answer:
Step-by-step explanation:
Let x represent Dan's age
3x be James'age
Paul 2(3x+x)=6x+2x
Suming all ages
x+3x+6x+2x=120
Solving for x
12x=120
x=10 (Dan's age)
3×=30 (James'age)
6×+2×=80(Paul's age)

Answer:-1/2
Step-by-step explanation:
16^x=1/4
(4^2)^x=4^(-1)

2x=-1
Divide both sides by 2
2x/2=-1/2
x=-1/2
