Answer:
72 purple tiles
Explanation:
If the green tiles which is 5 for every 8 tiles and we know there are 45 green tiles, we can find the answer by dividing. 45/9=5, since we know we multiplied 9 to gain 45 we can multiply the same number to 8 to find the amount of purple tiles in the mosaic. (I hope this helps)

Concept: Graph Analysis

Take a look at the first graph. Notice it goes through (0,-2) and the slope is 5/2 so the answer is A.Next to find the equation we look at the y-intercept and determine that its -2 and the slope is -5/2. Hence the answer is C

Step-by-step explanation:

Problem 1.

Start at (0, -2). Go up 5 and right 2. That is a slope of 5/2.

First choice.

Problem 2.

The y-intercept is (0, -2), so b = -2.

Start at (0, -2). Go down 5 and right 2. That is a slope of -5/2.

y = mx + b

y = -5/2 x - 2

Which expression best defines a rational number?

A. has a decimal form that can be rounded
B. has a decimal form that cannot be rounded
C. has a decimal form that is terminating or repeating
D. has a decimal form that is nonterminating and nonrepeating

Answers

A for sure because it can be

Rational numbers are terminating or repeating numbers. Therefore, option C is the correct answer.

We need to check from the options which expression best defines a rational number.

What are rational numbers?

Rational numbers: Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Rational numbers can be easily identified with the help of the following characteristics.

All integers, whole numbers, natural numbers, and fractions with integers are rational numbers.If the decimal form of the number is terminating or recurring as in the case of 5.6 or 2.141414, we know that they are rational numbers.In case, the decimals seem to be never-ending or non-recurring, then these are called irrational numbers.

So, from the definition, we understood that rational numbers are terminating or repeating numbers.

Therefore, option C is the correct answer.

Look at this inequality: 12−4x ≤ 20

Which of these shows the solution to this inequality?

Question options:

Answers

Answer: The last line is the answer

12 - 4x < 20

20 - 12 = 8

-4x = 8

-4/4 = 8/-4

x = -2

New inequality: x > -2

Step-by-step explanation:

The correct option is d. The solution to the linear  inequality 12 - 4x ≤ 20 is x ≥ -2 by solving the inequality.

To solve this inequality,  to isolate the variable x.

Step 1

subtract 12 from both sides of the inequality:

        [tex]12 - 12 - 4x \leq 20 - 12,[/tex]

which simplifies to

         [tex]-4x \leq 8.[/tex]

Step 2 :

Divide both sides of the inequality by -4. However, when  divide by a negative number, the direction of the inequality sign must be flipped. So   x ≥ -2, indicating that x is greater than or equal to -2.

Therefore, the solution to the inequality is x ≥ -2. The correct option is d.
