Answer:
x = 0
Step-by-step explanation:
First we set up our equation. From the picture we can see that:
11 + x + 1 = 2x + 12
Now we can gather our like terms:
x + 12 = 2x + 12
Lets subtract x from both sides to isolate the x on the left:
12 = x + 12
Next we subtract 12 from both sides
x = 0
Check the answer
11 + 0 + 1 = 2(0) + 12
12 = 0 + 12
12 = 12
Answer:

Step-by-step explanation:
So first we need to find how much a single ticket will cost.
Subtract the service fee to get how much it cost for 8 tickets.
229-13=216
Then divide that number by 8 to find how much a single ticket costs.
216÷8=27
1 ticket costs $27.
Multiply that by 15 to get how much 15 tickets cost.
27×15=405
Then add back the service fee.
405+13=418

Step-by-step explanation:
Let x be the number of minutes she can continue, since she's already 20 feet below the ocean surface and is diving at the rate of 20 ft/minute, her depth with respect to x would be
20 + 20x
But she doesn't want to reach more than 100 feet below the surface
