The answer to your question is 5 weeks
Step-by-step explanation:
Data
Ryan Miles
$150 $50
each week = $40 each week = $60
x = savings
y = time in weeks
Process
1.- Write an equation for Ryan savings
x = 40y + 150
2.- Write an equation for Miles savings
x = 60y + 50
3.- Solve the system by Equality
40y + 150 = 60y + 50
- Solve for y
40y - 60y = 50 - 150
-20y = -100
y = -100 / -20
y = 5
4.- Conclusion
After 5 weeks, they will have the same amount of money.

Answer:
6
Step-by-step explanation:
4n - 12 < 2n + 2 is for n=6
4×6 -12 < 2×6 +2
24 - 12 < 12 + 2
12 < 14 correct
for n=7
4×7 - 12 < 2×7 + 2
16 < 16 incorrect
for n=8
4×8 - 12 < 2×8 + 2
20 < 18 incorrect
for n=9
4×9 - 12 < 2×9 + 2
24 < 20 incorrect
so, only for n=6 is the expression true.
