Answer:
1) Add 3n to both sides
2) Subtract 5 from both sides
3) Divide both sides by 6
n=3
Step-by-step explanation:
3n+5=23-3n
+3n +3n
6n+5=23
-5 -5
6n=18
/6 /6
n=3
Answer:
1) 35
Step-by-step explanation:
1. First, you have to realize that a straight line is 180 degrees.
Why is this important to know? Well you know that all angles of a triangle added up together HAS to equal 180, it'll be a straight line
2. Add 40 and 105, this gives you 145.
3. Subtract 145 from 180, and you should get 35, which is x.
You can check this by adding 40, 105, and 35 together.
Answer:
7 < x < 17
Step-by-step explanation:
Solving the first equation:
x + 5 > 12
x > 7 (subtract 5 from both sides)
Solving the second equation:
x - 5 < 12
x < 17 (add 5 to both sides)
Now, combine the two equations:
x > 7 and x < 17 become
7 < x < 17
8 pieces of wood. It takes 6 inches to make 1 dowel, so with 4 feet (48 inches) you could make 8 dowels per board. You would need 7.5 boards to make 60, but you cant buy half a board, so the answer is 8
