Answer:
25 more hours
Step-by-step explanation:
First you need to make an equation
200+12x=500
Then you solve it by:
Subtracting 200 from both sides
12x=300
Then divide both sides by 12
x=25
Then you can check your answer by plugging in the number
200+12x25=500

Answer:
2. 1. 3. 4.
Step-by-step explanation:

Q=(c+d)/2
Multiply both sides by 2 to get rid of the 2
2×q=(c+d)
Subtract c from both sides to get rid of the c
2×q-c=d
Flip the equation around
d=2×q-c
