### If 8 - x = 4, and 10 + y = 12, then x - y = _____ ?

• A.

2

• B.

3

• C.

4

• D.

5

A. 2
Explanation
The given equations are 8 - x = 4 and 10 + y = 12. From the first equation, we can solve for x by subtracting 8 from both sides, which gives us -x = -4. Multiplying both sides by -1, we get x = 4. From the second equation, we can solve for y by subtracting 10 from both sides, which gives us y = 2. Finally, we can substitute the values of x and y into the equation x - y to find that 4 - 2 = 2. Therefore, the answer is 2.

### Twenty students brought animals to school for pet day. Eight students brought dogs, four students brought birds, two brought cats, and the rest brought other animals. What fraction of the students brought other animals?

• A.

or 3/10

• B.

or 6/14

• C.

or 10/12

• D.

or 3/20

A.  or 3/10
Explanation
Out of the twenty students, eight brought dogs, four brought birds, and two brought cats. This accounts for a total of 8 + 4 + 2 = 14 students. The remaining students, which is 20 - 14 = 6 students, brought other animals. Therefore, the fraction of students who brought other animals is 6/20, which can be simplified to 3/10.

### Jennifer and Jose each swam five laps in 15 minutes. At the same rate of speed, how long would they need in order to swim 35 laps?

• A.

35 minutes

• B.

75 minutes

• C.

105 minutes

• D.

175 minutes

C. 105 minutes
Explanation
If Jennifer and Jose each swim five laps in 15 minutes, it means they swim at a rate of 1 lap per 3 minutes. To find out how long they would need to swim 35 laps, we can multiply the rate by the number of laps. 1 lap per 3 minutes multiplied by 35 laps equals 105 minutes. Therefore, it would take them 105 minutes to swim 35 laps at the same rate of speed.

• A.

16 hours

• B.

18 hours

• C.

20 hours

• D.

22 hours

C. 20 hours
Explanation
The cat sleeps for 5/6 of the 24-hour day. To find the number of hours the cat sleeps, we can multiply 5/6 by 24. Simplifying this, we get (5/6) * 24 = (5 * 24) / 6 = 120 / 6 = 20 hours. Therefore, the cat sleeps for 20 hours.

### In a geography class of 24 students, each student had to select a state on which to give a three-minute report. How long did the presentation last to total ?

• A.

1 hour, 6 minutes

• B.

1 hour, 12 minutes

• C.

1 hour, 15 minutes

• D.

1 hour, 30 minutes

B. 1 hour, 12 minutes
Explanation
Each student had to give a three-minute report, and there are 24 students in the class. Therefore, the total time for all the presentations would be 3 minutes multiplied by 24 students, which equals 72 minutes. However, since there are 60 minutes in an hour, we need to convert 72 minutes to hours and minutes. Dividing 72 by 60 gives us 1 hour and a remainder of 12 minutes. Therefore, the total presentation time is 1 hour, 12 minutes.

• B.

50 minutes

• C.

60 minutes

• D.

70 minutes

A. 40 minutes
Explanation
Since Rebecca and Ian were driving at the same speed, we can assume that they covered the same distance in the same amount of time. Rebecca took 20 minutes to drive 15 miles, so Ian would take the same amount of time to drive double the distance. Therefore, it would take Ian 40 minutes to drive 30 miles.
