    • X = 5

    • X = -5

    • X = 1

    • NONE OF THE ABOVE

    Correct Answer
    A. X = 5
    Explanation
    The given equation is 3x - 5 = 10. To solve for x, we need to isolate it on one side of the equation. Adding 5 to both sides, we get 3x = 15. Dividing both sides by 3, we find that x = 5. Therefore, the correct answer is x = 5.

    There were 279 participants in the science fair.  About 2/3 of them were seventh graders.  Which of these is a reasonable estimate of the number of seventh graders taking part in the science fair?

    • 100

    • 150

    • 200

    • 250

    Correct Answer
    A. 200
    Explanation
    Since about 2/3 of the participants were seventh graders, a reasonable estimate of the number of seventh graders taking part in the science fair would be 2/3 of the total number of participants. Therefore, 2/3 of 279 is approximately 186. Since we need to choose from the given options, the closest option to 186 is 200. Hence, 200 is a reasonable estimate of the number of seventh graders taking part in the science fair.

    • $40

    • $60

    • $100

    Correct Answer
    A. $40
    Explanation
    Jessica had $115 and spent 1/3 of that amount on a new stereo. To find out how much she spent, we can divide $115 by 3, which gives us approximately $38.33. Since the answer choices are rounded estimates, the most reasonable estimate would be $40.

     3(x+6) = 6 

    • X = 12

    • X = -4

    • X = 4

    • X = 0

    Correct Answer
    A. X = -4
    Explanation
    To solve the equation 3(x+6) = 6, we need to distribute the 3 to both terms inside the parentheses. This gives us 3x + 18 = 6. Next, we can subtract 18 from both sides of the equation to isolate the variable term. This gives us 3x = -12. Finally, we divide both sides of the equation by 3 to solve for x, which gives us x = -4. Therefore, the correct answer is x = -4.

    • 1/9

    • 1/2

    • 1/4

    • 1/8

    Correct Answer
    A. 1/4
    Explanation
    The fraction 1/4 is greater than 1/6 because the numerator (1) is larger than the numerator of 1/6 (1), and the denominator (4) is smaller than the denominator of 1/6 (6). However, it is less than 1/3 because the numerator (1) is smaller than the numerator of 1/3 (1), and the denominator (4) is larger than the denominator of 1/3 (3). Therefore, 1/4 is the fraction that fits the given criteria.

    The number of teachers is directly proportional to the number of students.  When there are 224 students, there are 14 teachers.  how many teachers are there when there are 368 students?

    • 21 teachers

    • 23 teachers

    • 25 teachers

    • 27 teachers

    Correct Answer
    A. 23 teachers
    Explanation
    The given information states that the number of teachers is directly proportional to the number of students. This means that as the number of students increases, the number of teachers also increases proportionally.

    To find the number of teachers when there are 368 students, we can set up a proportion using the given information.

    224 students corresponds to 14 teachers.

    So, if we set up the proportion:

    224 students / 14 teachers = 368 students / x teachers

    Cross-multiplying, we get:

    224x = 14 * 368

    Simplifying, we find:

    x = (14 * 368) / 224

    Calculating this, we get x ≈ 23.

    Therefore, when there are 368 students, there will be approximately 23 teachers.

    Rate this question:

    • X = 6

    • X = -6

    • X = 12

    • X = 10

    Correct Answer
    A. X = 12
    Explanation
    To solve the equation 1/2 x + 4 = 10, we need to isolate the variable x. First, we subtract 4 from both sides of the equation to get 1/2 x = 6. Then, to get rid of the fraction, we multiply both sides by 2, resulting in x = 12. Therefore, the correct answer is x = 12.

    Mr. Rogers bought a small motorboat.  Traveling at a speed of 30 miles per hour, he could go 50 miles on a 6 gallon tank of fuel.  At that rate, how many gallons of fuel would he need for a 75 mile trip?

    • 7 1/2

    • 9

    • 12

    • 20

    Correct Answer
    A. 9
    Explanation
    Based on the given information, Mr. Rogers can travel 50 miles on a 6-gallon tank of fuel. To find out how many gallons of fuel he would need for a 75-mile trip, we can set up a proportion. We know that 50 miles is to 6 gallons as 75 miles is to x gallons. By cross-multiplying and solving for x, we find that x is equal to 9 gallons. Therefore, Mr. Rogers would need 9 gallons of fuel for a 75-mile trip.

    The Lauder Theatre uses 3 ushers for every 150 guests.  If the net concert is sold out, and the theater holds 992 people, approximately how many ushers will they need for the sold out concert?

    • 7 ushers

    • 20 ushers

    • 50 ushers

    • 331 ushers

    Correct Answer
    A. 20 ushers
    Explanation
    The Lauder Theatre uses 3 ushers for every 150 guests. If the theater holds 992 people, we can calculate the number of ushers needed by dividing the total number of guests by 150 and then rounding up to the nearest whole number. 992 divided by 150 is approximately 6.61. Rounding up, we get 7. Therefore, approximately 7 ushers will be needed for the sold-out concert. The correct answer of 20 ushers is not supported by the given information.

    The length of Sara's banner for Family Fun Night is 2 feet more than 1/2 the length of Alex's banner. Saras banner is 10 feet long.  What is the length of Alexs banner?

    • 8 feet

    • 12 feet

    • 16 feet

    • 20 feet

    Correct Answer
    A. 16 feet
    Explanation
    The length of Sara's banner is 2 feet more than 1/2 the length of Alex's banner. If Sara's banner is 10 feet long, we can set up the equation: 10 = (1/2)x + 2, where x represents the length of Alex's banner. By subtracting 2 from both sides and multiplying by 2, we get 16 = x. Therefore, the length of Alex's banner is 16 feet.
