Absolute value is defined as follows:

|x| = x if x ≥ 0 and -x if x < 0.

To make an equation using absolute value, you need to look for the following:

1) something where you use positive and negative numbers

2) something where changing the sign between positive and negative, or vice versa, doesn't affect the problem.

Choice A talks about price per gallons. You can't have negative money amounts so this one won't work.

Choice B talks about distances of walking. In math classes you can have negative distance, but not in reality. Nope.

Choice D talks about books. But books sold as a negative number means you bought them, and the meaning changes. Nope.

Choice C uses "plus or minus". It also talks about something that's approximate, and it's also a case where the signs won't matter. Bingo.


Thus choice C is best.

5. How many ways are there to choose seven cards from a deck of 52?
Fiesta28 [93]

Answer:

674,274,182,400

Step-by-step explanation:

In this particular situation, the first card can be chosen in 52 ways. The second card can be chose in 51 (because when you chose the first card, there were 51 left), you keep doing that seven times

So, 52*51*50*49*48*47*46

Hope this helps.

Which values are in the solution set of the compound inequality? Select two options
zhannawk [14.2K]

The values are in the solution set of the compound inequality are (-6, -3), (3, 8).

<h3>What is inequality?</h3>

Inequality is the phenomenon of unequal distribution of resources and opportunities among the given function.

To find the number that are solutions to the compound inequalities, the value of x is

First inequality:

4(x +3) ≤0

4x +12 ≤0

4x ≤-12

x ≤-3

The value of x lies in the interval = (-∞ , -3]

Second inequality:

x +1 >3

x>2

The value of x lies in the interval = (2 , ∞)

So, the interval solution is (-∞ , -3] U (2 , ∞)

Thus, the values are in the solution set of the compound inequality are (-6, -3), (3, 8).

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a
rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 =  45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>
