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 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.
w minus 8.8 equals 95.3 ; the water level of the dam last month was 104.1 meters.
w − 95.3 = 8.8; the water level of the dam last month was 86.5 meters.
Responses
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.
w minus 8.8 equals 95.3 ; the water level of the dam last month was 104.1 meters.
w − 95.3 = 8.8; the water level of the dam last month was 86.5 meters.
The correct equation is w = 95.3 - 8.8.
So, the water level of the dam last month was 86.5 meters.
Therefore, the answer is: w equals 95.3 minus 8.8; the water level of the dam last month was 86.5 meters.
So, the water level of the dam last month was 86.5 meters.
Therefore, the answer is: w equals 95.3 minus 8.8; the water level of the dam last month was 86.5 meters.
