1

Which of these numbers is a factor of 36?

69% Answer Correctly
19
26
9
12

Solution

The factors of a number are all positive integers that divide evenly into the number. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36.


2

What is \( \frac{5}{6} \) - \( \frac{6}{10} \)?

61% Answer Correctly
2 \( \frac{7}{30} \)
1 \( \frac{6}{9} \)
\(\frac{7}{30}\)
2 \( \frac{5}{8} \)

Solution

To subtract these fractions, first find the lowest common multiple of their denominators. The first few multiples of 6 are [6, 12, 18, 24, 30, 36, 42, 48, 54, 60] and the first few multiples of 10 are [10, 20, 30, 40, 50, 60, 70, 80, 90]. The first few multiples they share are [30, 60, 90] making 30 the smallest multiple 6 and 10 share.

Next, convert the fractions so each denominator equals the lowest common multiple:

\( \frac{5 x 5}{6 x 5} \) - \( \frac{6 x 3}{10 x 3} \)

\( \frac{25}{30} \) - \( \frac{18}{30} \)

Now, because the fractions share a common denominator, you can subtract them:

\( \frac{25 - 18}{30} \) = \( \frac{7}{30} \) = \(\frac{7}{30}\)

a(b + c) = ab + ac defines which of the following?

74% Answer Correctly

distributive property for division

distributive property for multiplication

commutative property for multiplication

commutative property for division


Solution

The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.

A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 10% off." If Roger buys two shirts, each with a regular price of $46, how much will he pay for both shirts?

57% Answer Correctly
$41.40
$52.90
$55.20
$87.40

Solution

By buying two shirts, Roger will save $46 x \( \frac{10}{100} \) = \( \frac{$46 x 10}{100} \) = \( \frac{$460}{100} \) = $4.60 on the second shirt.

So, his total cost will be
$46.00 + ($46.00 - $4.60)
$46.00 + $41.40
$87.40

If \( \left|x + 5\right| \) - 1 = -8, which of these is a possible value for x?

62% Answer Correctly
-12
-15
4
-3

Solution

First, solve for \( \left|x + 5\right| \):

\( \left|x + 5\right| \) - 1 = -8
\( \left|x + 5\right| \) = -8 + 1
\( \left|x + 5\right| \) = -7

The value inside the absolute value brackets can be either positive or negative so (x + 5) must equal - 7 or --7 for \( \left|x + 5\right| \) to equal -7:

x + 5 = -7
x = -7 - 5
x = -12
x + 5 = 7
x = 7 - 5
x = 2

So, x = 2 or x = -12.
