Any number divided by 1 is still that number (it stays the same).
So you can rewrite 280 as 280/1, which is a fraction.
With 280/1, you can also get an equivalent fraction by multiplying the numerator and denominator by a number, let's say 2.
So multiplying the numerator 280 by 2 would get 560, the denominator would be 2. So another equivalent fraction would be 560/2
The answer is 45 because on the bottom there is a 105 and since the 30 degrees is equal with the one across from it you do 180-105-30 or 105+30 then 180-135
Answer:
600/mph
Step-by-step explanation:
The value of n in the equation is 1
Step-by-step explanation:
The equation is 
(2n + 4) + 6 = -9 + 4(2n + 1)
At first we must do that:
1. Open the brackets in both sides
2. Add like terms
3. Solve to find n
L.H.S:
∵ (2n + 4) + 6 = -n - 2 + 6
∴ (2n + 4) + 6 = -n + 4
R.H.S:
∵ -9 + 4(2n + 1) = -9 + 8n + 4
∴ -9 + 4(2n + 1) = 8n - 5
∴ -n + 4 = 8n - 5
- Add 5 to both sides
∴ -n + 9 = 8n
- Add n to both sides
∴ 9 = 9n
- Divide both sides by 9
∴ n = 1
The value of n in the equation is 1
