Answer:
1. a/b = 2
2. a/b = 1/3
Step-by-step explanation:
3a=6b
We want to find a/b
Divide each side by b
3a/b=6b/b
3a/b = 6
Divide each side by 3
3a/3b =6/3
a/b = 2
15a=5b
We want to find a/b
Divide each side by b
15a/b = 5b/b
15a/b = 5
Divide each side by 15
15 a/15b = 5/15
a/b = 1/3
The max of Lauren's age --> the minimum of the others' ages, 1, 2 & 3

Answer:
y = -3x + 5
Step-by-step explanation:
You want it in y = mx + b form
-5 = -y - 3x
Add y to both sides
-5 + y = -y + y - 3x
-5 + y = -3x
Add 5 to both sides
- 5 + 5 + y = -3x + 5
y = -3x + 5
