Step-by-step explanation:
- 1/2(2n + 4) + 6= - 9 +4 (2n + 1)
If you can describe this as well as you have, you should be using Latex which is at the bottom of your editor when you ask the question
Remove the brackets.
-1/2 * 2n - 1/2 * 4 + 6 = - 9 + 8n + 4 Combine like terms.
-n - 2 + 6 = -9 + 8n + 4
-n + 4 = - 5 + 8n Add n from both sides.
4 = -5 + 8n + n
4 = -5 + 9n Add 5 to both sides
4 + 5 = 9n
9 = 9n Divide by 9
9/9 = 9n/9
n = 1

Step-by-step explanation:
We need to determine how much of the lawn Mel has to mow
1 lawn - 1/3 of the lawn = 3/3 - 1/3 = 2/3
We can use a ratio to solve
3/4 lawn 2/3 lawn
-------------- = ------------
1 hour x hours
Using cross products
3/4 x = 1 * 2/3
3/4x = 2/3
Multiply each side by 4/3
4/3 * 3/4x = 2/3 * 4/3
x = 8/9
8/9 hours
