To determine the number of hours,
h + 3
This equation represents that the total hours needed to complete her service program (the hours she still needs,
To determine the amount of money you had in your piggy bank before buying the toy, the correct equation is:
p - 13.32 = 25.70
This equation represents that the amount of money you had in your piggy bank (p) minus the cost of the toy ($13.32) equals the amount of money you had left ($25.70).
Now, let's solve for
Adding
Calculating the right side:
Therefore, there was $39.02 in the piggy bank before buying the toy.
To determine the number of balloons Alexa popped, the correct equation is:
n + 5 = 13
This equation states that the number of balloons Alexa popped (n) plus the number of balloons Krista popped (5) equals the total number of balloons popped (13).
Now, let's solve for
Subtracting 5 from both sides gives:
Calculating the right side:
Therefore, Alexa popped 8 balloons.
To determine the water level
w − 8.8 = 95.3
This equation indicates that the water level last month (w) minus the decrease in water level (8.8 meters) equals the current water level (95.3 meters).
Now, let's solve for
Adding 8.8 to both sides gives:
Calculating the right side:
Therefore, the water level of the dam last month was 104.1 meters.
