If \( \left|y - 6\right| \) + 3 = 7, which of these is a possible value for y?

62% Answer Correctly
-25
-1
10
-6

Solution

First, solve for \( \left|y - 6\right| \):

\( \left|y - 6\right| \) + 3 = 7
\( \left|y - 6\right| \) = 7 - 3
\( \left|y - 6\right| \) = 4

The value inside the absolute value brackets can be either positive or negative so (y - 6) must equal + 4 or -4 for \( \left|y - 6\right| \) to equal 4:

y - 6 = 4
y = 4 + 6
y = 10
y - 6 = -4
y = -4 + 6
y = 2

So, y = 2 or y = 10.


2

This property states taht the order of addition or multiplication does not mater. For example, 2 + 5 and 5 + 2 are equivalent.

60% Answer Correctly

associative

commutative

distributive

PEDMAS


Solution

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.

What is \( 6 \)\( \sqrt{125} \) - \( 5 \)\( \sqrt{5} \)

38% Answer Correctly
30\( \sqrt{125} \)
\( \sqrt{25} \)
30\( \sqrt{5} \)
25\( \sqrt{5} \)

Solution

To subtract these radicals together their radicands must be the same:

6\( \sqrt{125} \) - 5\( \sqrt{5} \)
6\( \sqrt{25 \times 5} \) - 5\( \sqrt{5} \)
6\( \sqrt{5^2 \times 5} \) - 5\( \sqrt{5} \)
(6)(5)\( \sqrt{5} \) - 5\( \sqrt{5} \)
30\( \sqrt{5} \) - 5\( \sqrt{5} \)

Now that the radicands are identical, you can subtract them:

30\( \sqrt{5} \) - 5\( \sqrt{5} \)
(30 - 5)\( \sqrt{5} \)
25\( \sqrt{5} \)


4

What is the least common multiple of 8 and 16?

72% Answer Correctly
47
58
55
16

Solution

The first few multiples of 8 are [8, 16, 24, 32, 40, 48, 56, 64, 72, 80] and the first few multiples of 16 are [16, 32, 48, 64, 80, 96]. The first few multiples they share are [16, 32, 48, 64, 80] making 16 the smallest multiple 8 and 16 have in common.

If there were a total of 350 raffle tickets sold and you bought 14 tickets, what's the probability that you'll win the raffle?

60% Answer Correctly
7%
1%
19%
4%

Solution

You have 14 out of the total of 350 raffle tickets sold so you have a (\( \frac{14}{350} \)) x 100 = \( \frac{14 \times 100}{350} \) = \( \frac{1400}{350} \) = 4% chance to win the raffle.
