Which expression is not equivalent to the other three?
AVprozaik [17]

Answer:

<em>4 + 7x – 2</em>

Step-by-step explanation:

<u>Equivalent Expressions</u>

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

2x + 2+ 2x + 3x -8=7x-6

Now for the second expression

4 + 7x -2=7x+2

The third expression simplifies to

-2 + 5x + 2x - 4=7x-6

Finally, this is the simplification for the expression

8x - x - 6=7x-6

As seen, the only expression not equivalent to the other three is 4 + 7x – 2

Which sentence below represents the number of test questions in the problem below?
katrin2010 [14]

Answer: there are 10 multiple choice questions and 15 short-answer questions

Step-by-step explanation:

Let x represent the number of multiple choice questions in the test.

Let y represent the number of short-answer questions in the test.

If the test has 25 questions, it means that

x + y = 25

Multiple-choice questions are worth 2 points, and short-answer questions are worth 4 points. The test is worth a total of 80 points. It means that

2x + 4y = 80 - - - - - - - -1

Substituting x = 25 - y into equation 1, it becomes

2(25 - y) + 4y = 80

50 - 2y + 4y = 80

- 2y + 4y = 80 - 50

2y = 30

y = 30/2 = 15

x = 25 - y = 25 - 15 = 10

A. The number of multiple-choice questions plus the number of short-answer questions is 25.
