An inequality that represents the following sentence: 45 more than a number is greater than 5 is

x-45>5

This is further explained below.

<h3>Write an inequality that represents the following sentence: 45 more than a number is greater than 5.?</h3>

Generally, An inequality is a relation in mathematics that makes a non-equal comparison between two numbers or other mathematical expressions. In other words, an inequality compares two numbers in a way that is not equal.

The most common use of this concept is to contrast the relative sizes of two integers using a number line.

In conclusion, An inequality that represents the following sentence: 45 more than a number is greater than 5 is

x-45>5

A book sold 36,600 copies in its first month of release. Suppose this represents 7.1% of the number of copies sold to date. How

pentagon [3]

Answer:

515,493 copies sold

Step-by-step explanation:

Since this is a ratio problem and we have three values and one variable that we need to find (copies sold to date) then we can use the Rule of three to solve this problem. We simply need to multiply the diagonal values and divide by the third value to get the variable. This can be seen below...

36,600 copies <=====> 7.1%

x copies <========> 100%

(36,600 * 100) / 7.1 = 515,492.96

Since the number of books cannot be a decimal we must round up to the nearest book sold, which would mean that the number of copies sold to date is 515,493 copies sold

Use the commutative property of multiplication to identify which expression is equivalent to 6(2)(x).

The commutative property is when you change the order but not the answer. To better understand what they are asking you, let's let x=1- 6 * 2 * 1=12; Answer A wouldn't be right because there are no 6,2, or x's. Remember you just change the ORDER not the GROUPING so Answer B is wrong too. Now Answer C and Answer D are left. Now you just need to look at the signs. 6(2) just means 6 TIMES 2 so pick the option with multiplication. So your answer is C. Hope I helped!
