Answer:
Judy is 16 years old
Step-by-step explanation:
J = Judy's age
A = Adams age
J = 2A
Six years ago (subtract 6 from the ages)
(J-6) = 5*(A-6)
Distribute
J-6 = 5A - 30
Substitute J = 2A
2A -6 = 5A -30
Subtract 2A from both sides
2A-2A -6 = 5A-2A -30
-6 = 3A -30
Add 30 to each side
-6+30 = 3A-30+30
24 = 3A
Divide by 3
24/3 = 3A/3
8 = A
Adam is 8 years old now
We need to find Judy's age
J = 2A
J = 2*8
J = 16
Judy is 16 years old
Answer:
|x − 3| = 2
Step-by-step explanation:
The difference between his maximum time and his average time is +2 hours.
x − 3 = 2
The difference between his minimum time and his average time is -2 hours.
x − 3 = -2
Using absolute values:
|x − 3| = 2
3x and 2x are alike terms, as they have the same variable
It’s the last option if you need an explanation just let me know!
