Due to excessive heat, the water level in a dam decreased by 8.8 meters last month. Now, the water level is 95.3 meters. Which equation represents the water level, w, of the dam last month? What was the water level last month?
The equation that represents the water level, w, of the dam last month is:
w - 8.8 = 95.3
To find the water level last month, we need to solve this equation for w.
Add 8.8 to both sides of the equation:
w - 8.8 + 8.8 = 95.3 + 8.8
This simplifies to:
w = 104.1
Therefore, the water level of the dam last month was 104.1 meters.
Let's assume the water level last month was represented by the variable "w0". We know that the water level decreased by 8.8 meters, so the equation can be represented as:
w = w0 - 8.8
Given that the current water level is 95.3 meters (w = 95.3), we can substitute this value into the equation to solve for w0:
95.3 = w0 - 8.8
To isolate w0, we can add 8.8 to both sides of the equation:
w0 = 95.3 + 8.8
Calculating this gives us:
w0 = 104.1
Therefore, the water level of the dam last month was 104.1 meters.
To find the water level of the dam last month, we can use the equation:
w = 95.3 + 8.8
Here, "w" represents the water level last month. By adding 8.8 to the current water level of 95.3 meters, we can determine the water level last month.
Simplifying the equation:
w = 104.1
Therefore, the water level of the dam last month was 104.1 meters.
