2.  1. What are the next two numbers in this pattern?1.2, 1.9, 2.6, 3.3, 4.0, …  A. 4.2, 4.9  B. 4.7, 5.4  C. 4.7, 5.7  D. 5.2, 5.9

3.  The correct answer is: B 4.7, 5.4  Step 1: Determine the pattern that the numbers follow. In this question, you added 0.7 to the previous number to arrive at the next number in the pattern.  Step 2: Add 0.7 to 4.0. = 4.7  Step 3: Add 0.7 to 4.7 = 5.4

4.  2. What is the missing number in this pattern? 60,58,56,54,____, 50, …  A. 59  B. 53  C. 52  D. 51

5.  2. The correct answer is C. 52  Step 1: Determine the pattern. In this set of numbers the pattern is to subtract 2 from the previous number.  Step 2: Subtract 2 from 54 to get 52.

6.  3: Solve for x: 8x = 72  A. 8  B. 9  C. 10  D. 11

7.  3. The correct answer is B. 9  Step 1: You need to isolate the variable. Therefore, you need to do the inverse operation. Determine which operation is shown (multiplication).  Step 2: The inverse of multiplication is division.  Step 3: Divide both sides by 8.  Step 4: x = 9

8.  4. What is the solution of this equation? x – 8 = 55  A. X = 42  B. X = 47  C. X = 58  D. X = 63

9.  4: The correct answer is D. X = 63  Step 1: You need to isolate the variable by doing the inverse operation. Since the operation listed is subtraction, you must do the inverse (addition) to each side.  Step 2: 55 + 8 = 63

10.  5: Kimberly writes 6 pages every 2 hours. At this rate, how many pages can Kimberly write in 5 hours?  A. 4  B. 8  C. 12  D. 15

11.  5. The correct answer is D. 15  Step 1: Determine the unit rate. Since she write 6 in 2 hours, divide 6 by 2 to get 3 pages in one hour.  Step 2: Multiply 3 pages by 5 hours and get 15.

12.  6: Identify the mathematical expression that models this word expression: six less than the quotient of a number and four  A. 6 – n 4C. n - 6 4  B. n + 6 D. 6 - 4 4 n

13.  7. The correct answer is: C. n - 6 4  Step 1: Read through the problem and pick out the important/key words. (Quotient and less)  Step 2: Write the expression as it reads using mathematical symbols.

14.  7:Solve for J: 4J = 36  A. 9  B. 32  C. 40  D. 144

15.  7: The correct answer is: A. 9  Step 1: Isolate the variable by performing the inverse operation to each side. Since the operation listed is multiplication, the inverse is division. Divide both sides by 4.  Step 2: 36 divided by 4 = 9.

16.  8A. Mark wrote the number pattern below: 10, 15, 20, 25, 30, ___, 40, …..  A. What is the rule for the pattern? The rule for pattern is to add 5 to the previous number to arrive at the following number.

17.  8B: What is the missing number in the pattern?  The missing number is 35

18.  8C: The seventh term in the pattern is 40. What are the eighth and ninth terms?  The eighth term is 45.  The ninth term is 50.

19.  Kalmi wrote the following word expression: Five less than a number is equal to seven.  Write a mathematical sentence that models the word sentence above. Let n represent the number.  N – 5 = 7

20.  9B: Solve Kalmi’s mathematical sentence. Show your work.  n = 12  Step 1: Isolate the variable by completing the inverse operation. The inverse of subtraction is addition. Add 7 + 5 to get 12. n = 12

21.  10A: The graph below shows the growth of Sayeed’s plant.  10A: How much does the plant grow in 1 week?  The plant grows 0.5 cm in 1 week.

22.  10B: How tall will the plant be after 10 weeks? Explain your reasoning.  The plant will be 5 cm tall.  Since we already had the unit rate of 0.5 cm in 1 week. We need to multiply the weeks by 10 to find the amount in 10 weeks. If we multiply the weeks, we must also multiply the growth by 10. 0.5 * 10 = 5.0
