Josh ran 14.8 km in the morning. After lunch, he continued running. When he finished the run, he had covered 31.1 km in all. Write an equation that can be used to find how far Josh ran after lunch.

Answers

14.8 + x =31.1
X equals how much he ran after lunch

Answer:

14.8 + x = 31.1

Step-by-step explanation:

This is the best equation to put as the answer.

If you want to solve it, this is how you would solve it.

14.8 + x = 31.1

Make it so that the variable x is by it's self.

14.8 + x - 14.8 = 31.1 - 14.8

x = 31.1 - 14.8

Now solve the subtraction problem.

x = 31.1 - 14.8 = 16.3

So, now you have your answer

x = 16.3

To make sure it's correct, use the addition method.

16.3 + 14.8 = 31.1

When using a pronoun to refer to a person, speakers must either specify a gender or say something like "he or she." Not only can this be cumbersome, but it means that there is no good pronoun choice when a person's gender is unknown to the speaker. Sweden addressed this problem in 2015 by adding a new pronounhenwhich refers to a person without specifying a male or female gender. Hen does not replace the Swedish pronouns han, meaning "he," or hon, meaning "she"; it simply adds another option.
