Krista and Alexa played balloon darts in a school fair. Krista popped 5 balloons and Alexa popped n balloons. Together, they popped a total of 13 balloons. Which equation can be used to determine the number of balloons Alexa popped? How many balloons did she pop?(1 point)Responsesn + 13 = 5; Alexa popped 8 balloons.n plus 13 equals 5 ; Alexa popped 8 balloons.n − 13 = 5; Alexa popped 18 balloons.n minus 13 equals 5 ; Alexa popped 18 balloons.n − 5 = 13; Alexa popped 18 balloons.n minus 5 equals 13 ; Alexa popped 18 balloons.n + 5 = 13; Alexa popped 8 balloons.
To determine the number of balloons Alexa popped, we can use the equation n + 5 = 13.
Subtracting 5 from both sides of the equation, we get:
n = 8
Therefore, Alexa popped 8 balloons.
The correct equation is: n + 5 = 13; Alexa popped 8 balloons.
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)Responsesw + 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 + 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 − 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 − 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
To represent the water level, w, of the dam last month, we can use the equation w - 8.8 = 95.3.
Adding 8.8 to both sides of the equation, we get:
w = 104.1
Therefore, the water level of the dam last month was 104.1 meters.
The correct equation is: w - 8.8 = 95.3; the water level of the dam last month was 104.1 meters.
The correct equation to use to determine the number of balloons Alexa popped is n + 5 = 13. To understand why, let's break down the problem:
We are given that Krista popped 5 balloons. We are also given that Alexa popped n balloons. Together, they popped a total of 13 balloons.
To determine the number of balloons Alexa popped, we can set up an equation using the information given. Since we know that Alexa popped n balloons, we can represent that as n. Additionally, we know that the total number of balloons popped by both Krista and Alexa is 13, so we can represent that as 13.
The equation becomes: n + 5 = 13.
To find the value of n (the number of balloons Alexa popped), we need to solve for n. Simplifying the equation, we subtract 5 from both sides:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons.
The correct answer is:
n + 5 = 13; Alexa popped 8 balloons.
