Question

, of the dam last month? What was the water level last month?(1 point)
Responses

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.
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.

Answer 1

To find the water level of the dam last month, we can set up the equation based on the information provided. The water level decreased by 8.8 meters to reach the current level of 95.3 meters.

Let \( w \) be the water level last month. The relationship can be expressed as:

\[ w - 8.8 = 95.3 \]

Now, we can solve for \( w \):

\[ w = 95.3 + 8.8 \] \[ w = 104.1 \]

So, the correct equation is:

w − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
