2x + 6 < x + 20
- x - x
x + 6 < 20
- 6 - 6
x < 14
Solution Set: (-∞, 14)
Answer:
The number is 220
Step-by-step explanation:
Let n represent the number
10(2) + n = 240
20 + n = 240
240 - 20 = 220
n = 220
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
