Algebra G Practice Mastery Test 1 - Quiz

Some important notes about the Algebra G Mastery Test: While this practice test is multiple choice, the REAL test is a free-response. Work must be shown for each problem, and the work shown must support the resulting answers (i.e., problems with incorrect work leading to a correct answer will be marked as WRONG). A "passing" grade is 90%, however problems are grouped as shown in the. Pdf document showing a sample test: 10 problems total, and 9/10 problems must be correct. The test may be taken multiple times, however no more than once per day.

  1/5
- C.
  
  1/4
- D.
  
  No solution
- E.
  
  -3/4
Correct Answer
C. 1/4

Explanation
The answer is 1/4 because when solving the equation, we need to find the value of x that satisfies the equation. In this case, there is only one value that makes the equation true, which is x = 1/4. Therefore, 1/4 is the correct answer.

  None of these
Correct Answer
A. 69

Explanation
The given answer, 69, is the correct answer because it is the only option that makes sense in the context of finding the area. The other numbers listed do not relate to finding an area and are likely unrelated to the question. Therefore, 69 is the most logical choice for the correct answer.

Correct Answer
D. 52

Explanation
The correct answer is 52. The given options are numbers, and the question asks for the perimeter. However, since there are no shapes or figures mentioned, it is not possible to determine the perimeter. Therefore, the answer cannot be determined based on the given information.

^-12 - ^-15 =

Correct Answer
3

Explanation
The given expression is -12 minus the opposite of -15. The opposite of -15 is +15. So, -12 minus +15 can be rewritten as -12 + 15. When we add these two numbers, we get 3 as the result.

^-42 ÷ 7 =

Correct Answer
-6

Explanation
The given expression is a division problem. When -42 is divided by 7, it results in -6. This is because when a negative number is divided by a positive number, the quotient is negative. Therefore, -42 divided by 7 equals -6.

  E
- F.
  
  None of these
Correct Answer
C. C

Explanation
The graph that shows y = -2x + 4 is graph c. This is because the equation y = -2x + 4 represents a linear function with a slope of -2 and a y-intercept of 4. Graph c is the only graph that has a slope of -2 and passes through the point (0, 4), which represents the y-intercept. Therefore, graph c is the correct representation of the equation y = -2x + 4.

Factor 12x+14

Correct Answer
2(6x+7)

Explanation
The given expression can be factored by taking out the greatest common factor, which is 2. By applying the distributive property, we can multiply 2 with each term inside the parentheses, resulting in 2 multiplied by 6x and 2 multiplied by 7. Therefore, the factored form of 12x+14 is 2(6x+7).

Multiply. Leave your answer as an improper fraction.

Correct Answer
13/15

Explanation
Since the question asks to multiply, the answer will be the same as the given fraction 13/15. Multiplying any number by 1 does not change its value, so the fraction remains the same. Therefore, the answer is 13/15.

  F)
- F.
  
  None of these
Correct Answer
C. C)

Explanation
There are two possible answers to this problem, depending on whether Allie has $x (in which case Terri has $x+3, making the total 2x+3) or Terry has $x (in which case Allie has $x-3, making the total 2x-3). Either answer is correct, however for the purposed of a multiple choice test, only one option was made available.

  $7.50

  $18
- E.
  
  $12.50
- F.
  
  None of these
Correct Answer
B. $9

Explanation
Terry has $3 more than Allie, so if Allie has x amount of money, Terry must have x + $3. Together, they have $21, so we can set up the equation x + (x + $3) = $21. Simplifying this equation, we get 2x + $3 = $21. Solving for x, we subtract $3 from both sides and divide by 2, giving us x = $9. Therefore, Allie has $9.
