Example Questions
Example Question #181 : Variables
Add the following:
In the problem
we will first insert a coefficient on the second term. When a variable stands alone, it has a coefficient of 1. So,
When adding variables, we can look at the variables as objects, then combine those objects.
Now, we can think of the variable a as cars. So, we can look at it as
We can think of it like this: If we see 5 cars pass by us on the road, and we see 1 more car pass us, how many cars have passed us? The answer is 6. There were 6 cars that passed us. So,
We add variables the same way.
Example Question #41 : How To Add Variables
Add the following:
When adding variables, we can look at the variables as objects. So, in the problem
we can think of x as books. So, we can write it like this
We can think of it like this. We have 4 books and we borrow 2 more books. How many books have we borrowed?
We have borrowed 6 books.
We can add variables the same way.
Example Question #42 : How To Add Variables
Add the following:
When adding variables, we can look at the variables as objects.
So, in the problem
we can think of the variable a as apples. So, we can write it like
We can think of the problem like this: We have 2 apples, and we go to the store and buy 3 more apples. How many apples do we have now? We have 5 apples. So, we can solve it like
We add variables the same way. So,
Example Question #41 : How To Add Variables
Combine the following:
To add variables, we will look at the variables like objects. So, in the problem
we can think of the variable a as airplanes. So, we can write it like this:
We can think of the problem like this: We are outside and we see 5 airplanes in the sky. Throughout the day, we see 6 more airplanes. How many airplanes do we see all day? We see 11 airplanes. So,
We add variables the same way.
Example Question #192 : Operations
Combine the following:
To add variables, we can think of the variables like objects. So, in the problem
we can think of the variable s as snakes. So, we can write it like this:
We can think of it like this: We are at the zoo. We see 2 snakes in a pit. We walk a little more, and we see 8 more snakes. How many snakes have we seen at the zoo? We have seen 10 snakes. So,
We add variables the same way:
Example Question #193 : Operations
Combine the following:
To add variables, we will look at the variables like they are objects. So, in the problem
we can think of b as books. So, we can write it like this:
We can think of the problem like this: You have borrowed 2 books from the library. You go back, and you borrow 7 more books. How many total books have you borrowed? You have borrowed a total of 9 books. So,
We add variables the same way. We get
Example Question #2301 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Combine the following:
When combining variables, we can think of the variables as objects. So, in the problem
we can think of the variable m as movies. So, we can write it like this:
We can read it like this: We have 2 movies. We go to the store, and we buy 3 more movies. How many movies do we have now? We have 5 movies. So,
We add variables the same way.
Example Question #191 : Variables
Combine the following:
To add variables, we will look at the variables like they are objects. So, in the problem
we can think of the variable b as books. So, we can write the problem as
So, we can read the problem like this: We have borrowed 2 books from the library. We go back to the library and borrow 5 more books. How many total books have we borrowed from the library? We have borrowed 7 books. So,
We add variables the same way.
Example Question #196 : Operations
Combine the following:
To add variables, we will look at the variables like objects.
So, in the problem
we can think of the variable p as potatoes. So, we can write it like
We can read the problem like this: We go to the store to buy 5 potatoes. We realize we need more, so we buy 5 more potatoes. How many potatoes did we buy in total? We bought 10 potatoes. So,
We can add variables the same way.
Example Question #197 : Operations
Combine the following:
When adding variables, we will look at the variables like objects. So, in the problem
we can think of the variable p as pictures. So, we can write it like this:
We can read it like this: We have taken 9 pictures with our new camera. We walk around for a while, and we take 6 more pictures. How many pictures have we taken in total? We have taken 15 pictures. So,
We add variables the same way. So,
