kids

Answer 1

The equation to find the number of kids at the reunion is k + 30 = 75. By subtracting 30 from both sides, we find that there are 45 kids at the reunion.

Step-by-step explanation:

To find out how many kids k are at the reunion, we need to use the information provided to set up an equation.

We are told that Alexa hands out 75 watermelon slices in all, and that she gives a slice to each kid and to 30 adults. This allows us to create the following equation:

k + 30 = 75

To solve for k, the number of kids, we will subtract 30 from both sides of the equation:

• k + 30 - 30 = 75 - 30
• k = 45

Therefore, there are 45 kids at the reunion.
