Simplify the expression\(\frac{2x^{-1}y}{x^3z}\) for \(x=2\), \(y=8\), and \(z=-1\).

Answers

Answer 1

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

Answer 2

Step-by-step explanation:

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

4/5y - 8 = 2/5y + 16

Answers

Answer:

y=60

Step-by-step explanation:

trust

y = 60

Step-by-step explanation:

Step 1: Group all the x terms on the left side of the equation

Subtract y from both sides:

4/5y - 8 = 2/5y + 16

4/5y - 8 - 2/5y = 2/5y + 16 - 2/5y

2/5y - 8 = 2/5y + 16 - 2/5y

2/5y - 8 = 16

Step 2: Group all constants on the right side of the equation

Add 8 to both sides of the equation:

2/5y - 8 = 16

2/5y - 8 + 8 = 16 + 8

2/5y = 16 + 8

2/5y = 24

Step 3: Isolate the x

Multiply both sides by inverse fraction 52

2/5y = 24 5/2

2/5y 5/2 = 24

y = 24 5/2

y = 60

Question 3 options:

Answers

The first and the second sequence are arithmetic and geometric sequence, respectively

The first number in both sequences is 14

How to determine the first number?

From the question, we have the following rules

Rule 1

Start = 7

Multiply by 2

Rule 2

Start = 8

Add = 2

So, the numbers in the sequence are:

Rule 1: 7, 14, 28, 56......

Rule 2: 8, 10, 12, 14, .....

By comparing the numbers in the sequence, we can see that the first number in both sequences is 14

The ratio of the number of Malay students to the number of Indian students to the
number of Chinese students in a school is 5:4:8.
There are a total of 468 Indian and Chinese students.
What is the total number of students?
Ans:

Answers

Answer:

663

Step-by-step explanation:

the total number of students can be determined using this equation :

(total ratio of Chinese and Indian students / total ratio of students) x n = 468

total ratio of Chinese and Indian students = 4 + 8 = 12

total ratio of students 4 + 8 + 5 = 17

N = TOTAL NUMBER OF STUDENTS

12/17) x n = 468

multiply both sides of the equation by 17/12

n = 663

Zach's teammates were late to practice last week. According to Khan Academy the answer is 3.5.

The mean number of times Zach's teammates were late to practice last week is 3.5

What is dot plot?

A dot plot visually groups the number of data points in a data set based on the value of each point.

Given that, the following dot plot shows how many times each teammate was late to practice last week.

We need to find mean,

Total elements = 2 + 4 + 4 + 4 = 14

Data points = 4

Mean = 14 / 4 = 3.5

Hence, the mean number of times Zach's teammates were late to practice last week is 3.5
