To solve for x in the equation -5x + 2 = 67, we want to isolate x on one side of the equation.
First, let's get rid of the constant term on the left side by subtracting 2 from both sides:
-5x + 2 - 2 = 67 - 2
This simplifies to:
-5x = 65
Next, we want to get x alone on one side of the equation. To do this, we divide both sides by -5:

What is the first step in solving the equation:
20 = 6x - 4
20 = 6x - 4
To solve the equation 20 = 6x - 4, the first step is usually to isolate the variable term (the term containing x) on one side of the equation.
In this case, we can add 4 to both sides of the equation:
20 + 4 = 6x - 4 + 4
This simplifies to:
24 = 6x
Now, the variable term (6x) is isolated on one side of the equation, so we can proceed to solve for x by dividing both sides by 6.
(24)/6 = (6x)/6
This simplifies to:
4 = x
Therefore, the solution to the equation is x = 4.
In this case, we can add 4 to both sides of the equation:
20 + 4 = 6x - 4 + 4
This simplifies to:
24 = 6x
Now, the variable term (6x) is isolated on one side of the equation, so we can proceed to solve for x by dividing both sides by 6.
(24)/6 = (6x)/6
This simplifies to:
4 = x
Therefore, the solution to the equation is x = 4.

In Atlanta, the temperature was -2^. F in the morning in the winter. There was a winter storm, and the temperature dropped 10 degrees. What is the temperature now?(1 point)
If the temperature in Atlanta was -2°F in the morning during the winter and then dropped 10 degrees, we need to subtract 10 from -2°F to find the new temperature.
-2°F - 10°F = -12°F
Therefore, the temperature now is -12°F.
-2°F - 10°F = -12°F
Therefore, the temperature now is -12°F.

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?(1 point)
To calculate how much the climber needs to descend to return to his original starting point, we need to find the difference between the total amount he climbed and the total amount he descended.
The climber starts at an elevation of 380 ft and climbs 182 ft at the first rest stop, and then climbs another 208 ft at the second rest stop. Therefore, the total amount he climbed is:
380 + 182 + 208 = 770 ft.
If the climber now descends 235 ft, we subtract this from the total climbed:
770 - 235 = 535 ft.
Hence, in order to return to the original starting point, the climber needs to descend 535 ft.
The climber starts at an elevation of 380 ft and climbs 182 ft at the first rest stop, and then climbs another 208 ft at the second rest stop. Therefore, the total amount he climbed is:

If the climber now descends 235 ft, we subtract this from the total climbed:
770 - 235 = 535 ft.
Hence, in order to return to the original starting point, the climber needs to descend 535 ft.
Tickets to the baseball game are on sale for $1.50 off the regular price. Dea buys 6 tickets. If her total cost is $51, how much is the regular price of each ticket?(1 point)
To solve this problem, we can set up an equation based on the given information.
Let's assume the regular price of each ticket is represented by the variable "x."
Since Dea buys 6 tickets and the total cost is $51, we can set up the equation:
6(x - 1.50) = 51
Next, we can simplify the equation:
6x - 9 = 51
To isolate the variable term, we add 9 to both sides of the equation:
6x - 9 + 9 = 51 + 9
This simplifies to:
6x = 60
Finally, to solve for x, we divide both sides by 6:
(6x)/6 = 60/6
This simplifies to:
x = 10
Therefore, the regular price of each ticket is $10.
Let's assume the regular price of each ticket is represented by the variable "x."
Since Dea buys 6 tickets and the total cost is $51, we can set up the equation:
6(x - 1.50) = 51

6x - 9 = 51
To isolate the variable term, we add 9 to both sides of the equation:
6x - 9 + 9 = 51 + 9
This simplifies to:
6x = 60
Finally, to solve for x, we divide both sides by 6:
(6x)/6 = 60/6
This simplifies to:
x = 10
Therefore, the regular price of each ticket is $10.

20(2x - 8) = 440
20(2x - 8) = 440
