Answer:
1a and 2a
Step-by-step explanation:
In the first one, you should write an expression to help you picture what is happening. Since a test score is 4 times a quiz score which is x, a test score will be 4x. And since there are also 2 quizzes we should do 2x or just x + x. We then add the test score points and the quiz score points.
Here is the first way:
4x + 2x = 6x
Here is the second way:
4x + x + x = 6x
6x is your answer!
In the second one, you should also write an expression. Since a novel costs 6 more than a textbook which is represented by x, we will represent it the cost of a novel like this: x + 6. And since there is also one textbook we will just mark that as x. Now all we need to do is add them up/
This is what it will look like:
x + 6 + x = 2x + 6
2x + 6 is your answer!
