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?(1 point)
Responses
w − 95.3 = 8.8; the water level of the dam last month was 86.5 meters.
w minus 95.3 equals 8.8 ; the water level of the dam last month was 86.5 meters.
w + 95.3 = 8.8; the water level of the dam last month was 104.1 meters.
w plus 95.3 equals 8.8 ; the water level of the dam last month was 104.1 meters.
w + 8.8 = 95.3; the water level of the dam last month was 86.5 meters.
w plus 8.8 equals 95.3 ; the water level of the dam last month was 86.5 meters.
w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
To find the equation that represents the water level, w, of the dam last month, we need to use the given information. The water level in the dam decreased by 8.8 meters and is currently 95.3 meters. So, the equation would be:
w - 8.8 = 95.3
To solve for w, we need to isolate the variable w by moving the -8.8 to the other side of the equation. In this case, we add 8.8 to both sides:
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.
The correct option is:
w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
