Solve for n :
N=9
...........
Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is

Since you pay $15 per four, plus the fee. We can solve this equation for the fee:

If we plug c=195 and h=9, we have

Answer:
-0.45 or 9/20
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
9x - 8(x - 6) = 52
Step 2: Solve for <em>x</em>
- Distribute -8: 9x - 8x + 48 = 52
- Combine like terms: x + 48 = 52
- Subtract 48 on both sides: x = 4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(4) - 8(4 - 6) = 52
36 - 8(-2) = 52
36 + 16 = 52
52 = 52
Since a triangles total angle is 180°, to find the answer you would subtract the 2 angles you are given from 180. 180-56-36= 88°, this being your answer.
