A mountain climber starts a climb at an elevation of 380 ft. above sea level. At his first rest stop he has climbed 182 ft., and by his second rest stop he has climbed another 208 ft. It is getting late in the day, so the climber starts his way down the mountain. If the climber descends 235 ft, how much does he need to descend to return to his original starting point?

Using the order of operations (PEMDAS), we simplify the expression step by step:
First, we perform the operation within the parentheses: 1 - 15 = -14.
Next, we multiply -2 by -14: -2 * -14 = 28.
Then, we divide 28 by 4: 28 / 4 = 7.
Finally, we subtract 7 from 13: 13 - 7 = 6.
Therefore, the simplified expression is 6.

To simplify the expression, we distribute the negative sign to the terms inside the second set of parentheses:
(2x + 2) - (3x + 11)
= 2x + 2 - 3x - 11
Next, we combine like terms:
= (2x - 3x) + (2 - 11)
= -x - 9
Therefore, the simplification of the expression (2x + 2) - (3x + 11) is -x - 9.
(2x + 2) - (3x + 11)
= 2x + 2 - 3x - 11
Next, we combine like terms:
= (2x - 3x) + (2 - 11)
= -x - 9
Therefore, the simplification of the expression (2x + 2) - (3x + 11) is -x - 9.

Let's call the unknown number "x".
Twice the number, increased by 3, can be written as "2x + 3".
So the equation is: 2x + 3 = 7.
To solve for x, we need to isolate the variable on one side of the equation.
First, subtract 3 from both sides of the equation:
2x + 3 - 3 = 7 - 3,
2x = 4.
Next, divide both sides of the equation by 2:
(2x) / 2 = 4 / 2,
x = 2.
Therefore, the unknown number is x = 2.

If the temperature in Atlanta was initially -2°F and dropped 10 degrees due to the winter storm, we can find the new temperature by subtracting 10 from -2°F:
-2°F - 10°F = -12°F
Therefore, the temperature now in Atlanta is -12°F.
-2°F - 10°F = -12°F
Therefore, the temperature now in Atlanta is -12°F.

To solve the equation x/7 - 47 = -6, Shawn would subtract or isolate x/7 from the equation, not multiply.
He would add 47 to both sides to eliminate the constant term on the left side of the equation:
x/7 = 41.
And then multiply both sides by 7 to isolate the variable x:
7 * (x/7) = 7 * 41,
x = 287.
Therefore, the correct step would be to subtract or divide. I apologize for the confusion in the previous response.

I apologize for the confusion. In this case, the correct step is to add, not subtract or divide. Adding 47 to both sides of the equation allows you to isolate the variable and solve for its value.
x/7 - 47 + 47 = -6 + 47
This simplifies to:
x/7 = 41
Then, multiplying both sides of the equation by 7 gives:
7 * (x/7) = 7 * 41
The 7s on the left side cancel out, leaving:
x = 287
Therefore, the correct step would be to add, not subtract or divide.
x/7 - 47 + 47 = -6 + 47
This simplifies to:
x/7 = 41

To determine how much the mountain climber needs to descend to return to his original starting point, we need to calculate the net elevation change. Here's the calculation:
Starting elevation: 380 ft.
Elevation gained at the first rest stop: 182 ft.
Elevation gained at the second rest stop: 208 ft.
Elevation descent: -235 ft.
To find the total elevation change, we add up the elevation gained and subtract the elevation descent:
Total elevation change = (380 + 182 + 208) - 235
Total elevation change = 770 - 235
Total elevation change = 535 ft.
Therefore, the mountain climber needs to descend 535 ft to return to his original starting point.

Let's assume that the regular price of each ticket is x dollars.
Since Dea buys 6 tickets, her total cost will be 6 times the regular price minus the discount of $1.50 per ticket. This can be represented as:
6x - 6(1.50) = 51
Now, we can simplify the equation and solve for x:
6x - 9 = 51
Adding 9 to both sides:
6x = 60
Dividing both sides by 6:
x = 10
Therefore, the regular price of each ticket is $10.
