Note that there are 24 hours in 1 day, and 60 minutes in 1 hour
First, multiply 25 with 24
25 x 24 = 600
Next, add 600 with 9 hours
600 + 9 = 690
Note that there are 60 minutes in 1 hour. Divide 7 minutes with 60
7/60 = ~0.12 (rounded)
~690.12 hours is your answer
hope this helps

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 7
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 7 = -x + 5
- [Addition Property of Equality] Isolate <em>x</em> terms: 3x - 7 = 5
- [Addition Property of Equality] Isolate <em>x</em> term: 3x = 12
- [Division Property of Equality] Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -x + 5
- Substitute in <em>x</em>: y = -4 + 5
- Add: y = 1
The coefficient of b is h/2. Multiply the equation by the reciprocal of that.
(2/h)A = (2/h)·(h/2)·b
b = 2A/h . . . . . simplify
