To find the correct equation and water level last month, let's translate the given situation into an algebraic equation.
It is given that 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. We are to denote the water level last month as \( w \).
The equation should represent the fact that when you subtract 8.8 meters from last month's water level \( w \), you get the current water level of 95.3 meters. Mathematically, this can be expressed as:
\[ w - 8.8 = 95.3 \]
Solve this equation for \( w \) to find the water level last month:
\[ w = 95.3 + 8.8 \]
\[ w = 104.1 \]
Therefore, the water level of the dam last month was 104.1 meters.
The correct choice that represents the situation is:
A. w - 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
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
A.w- 8.8 =95.3; the water level of the dam last month was 104.1 meters
B. w-95.3 =8.8; the water level of the dam last month was 86.5
C. W+8.8=95.3; the water level of the dam last month was 86.5 meters
D. W+ 95.3=8.8; the water level of the dam last month was 104.1 meters
