Joaquin weighs his dog by weighing himself while holding the dog. Their total weight is 237 pounds. Joaquin weighs 156 pounds. Use [tex]$d$[/tex] for the dog's weight. Which equation shows the dog's weight?

a. [tex]d + 237 = 156[/tex]

b. [tex]d - 156 = 237[/tex]

c. [tex]d + 156 = 237[/tex]

Answer :

To find the dog's weight, we can set up an equation based on the information given:

1. Start with the total weight of Joaquin and his dog together, which is 237 pounds.

2. We know that Joaquin alone weighs 156 pounds.

3. If we let [tex]\( d \)[/tex] represent the dog's weight, we can write an equation by adding Joaquin's weight and the dog's weight to equal the total weight:
[tex]\[
d + 156 = 237
\][/tex]

4. The correct choice that matches this equation from the options given is:
[tex]\[
\text{c. } d + 156 = 237
\][/tex]

This equation correctly represents the situation, where the dog's weight ([tex]\( d \)[/tex]) added to Joaquin's weight (156 pounds) results in their combined weight of 237 pounds.
