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.
w minus 8.8 equals 95.3 ; the water level of the dam last month was 86.5 meters.
The correct equation to determine the number of balloons Alexa popped is n + 5 = 13. To understand why, we can use the given information that Krista popped 5 balloons, and together they popped a total of 13 balloons. Since we need to find the number of balloons Alexa popped (represented as n), we can set up an equation.
Let's break down the equation: n + 5 = 13. Here, n represents the number of balloons Alexa popped, and 5 represents the number of balloons Krista popped. The sum of these two quantities should equal the total number of balloons popped, which is 13.
Now, let's solve the equation:
n + 5 = 13
Subtract 5 from both sides of the equation:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons.
