SAT考试数学练习题第6套参考答案:

Explanation:

The only even numbers in the list are 2 and 4, but 4 is not a prime. So 2 can be used to illustrate the statement that all primes are not odd.

Explanation:

The sum of three consecutive integers can be written as n + (n + 1) + (n + 2) = 3n + 3

If the sum is 24, we need to solve the equation 3n + 3 = 24; 3n = 21; n = 7

The greatest of the three numbers is therefore 7 + 2 = 9

Explanation:

Since the cube lies between the number and its square on the number line, we must be looking for a negative fraction (between 0 and -1 on the number line). Only -2/5 is a negative fraction. (Try for yourself the results of squaring and cubing negative numbers less than -1, numbers greater than 1, positive fractions, 1 and -1, so that you can deal with all similar questions).

Explanation:

The maximum number of bows will be 4 yards (= 4 x 36 inches) divided by 15 inches.

This gives 9.6. But as a fraction of a bow is no use, we can only make 9 bows.

Explanation:

The numbers will be 203, 213, 223, 233, 243, 253, 263, 273, 283, 293, then all the numbers from 300 to 399 inclusive.

Explanation:

Plug the values 3 and 5 from the question into the answer choices to check whether you get 15 and 45 respectively.

Starting with A: 4x + 3 works with 3 ( 4 x 3 + 3 = 15) but not with 5 (4 x 5 + 3 = 23)

You can check the rest yourself….
