An equation shows the equality of two variables while an inequality shows the inequality of two variables.

Answer 2

Answer: Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

What is an inequality?

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.

Given is an inequality, x/10+6 ≥ 8

Rules for manipulating inequalities

Rule 1.) Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged.

Rule 2.) Multiplying or dividing both sides by a positive number leaves the inequality symbol unchanged.

Solving,

x/10+6 ≥ 8

x/10+6-6 ≥ 8-6

x/10 ≥ 2

10×x/10 ≥ 2×10

x ≥ 20

Hence, The solution of the inequality is x ≥ 20

Answer:

B. 3m^6 - 3m^3 - 2m^2

Step-by-step explanation:

Step 1: (6m^8 - 6m^5 - 4m^4)/2m^2

Step 2: (6m^8/2m^2) + (-6m^5/2m^2) + (-4m^4/2m^2)

Step 3: 3m^6 - 3m^3 - 2m^2

1) Given equation

2) You can imagine this fraction as (6m^8 - 6m^5 - 4m^4) multiplied by 1/(2m^2), so you can think of it like multiplying a monomial by a trinomial where you multiply the monomial by each term. In this step you multiply 1/(2m^2) by each of the terms in the trinomial.

3) In this step, you divide the terms in the parenthesis. You first divide the constants (ex: 6÷2=3 in (6m^8/2m^2)), and then you divide the variable exponents (ex: m^8÷m^2=m^6 in (6m^8/2m^2)).

In a class of 18 students, 5 have a brother and 11 have a sister. There are 5 students who do not have any siblings. What is the probability that a student has a sister given that they do not have a brother?

Answers

I think the images should make sense. If not, just comment, I’ll be here. (It’s only letting me insert one image so I’ll have to exp this part) once you’ve filled the two way table in, you circle the two squares that Apple to the situation. In this case, which ones don’t have a brother? The top right and bottom right fit that bill. Then you divide the number of students that actually have a sister but the two squares (added together) that do t have a brother. So it’d be 5/10 which is .5 for an answer

So triangles have a sum of 180° and in an isosceles triangle, two of the angles are equal. If we have one angle that measures 130°, the other two have to add up to 50°. Since the two are equal, the only answer can be 25°!

For a transaction, it will accept any number of items (not known in advance) and any number of payments of different payment types (not known in advance). For each transaction, it calculates the total including a 7% sales tax and keeps prompting for a payment until the total has been paid. It also determines if any change is required. Thus, a transaction is responsible for calculating the amount of money that needs to be paid, accepting money, and generating a receipt. A receipt holds information about a transaction so that it can display how much each item cost, how the transaction was paid for, etc. (see example outputbelow).Payment type includes CASH, DEBIT_CARD, CREDIT_CARDandCHECK. Each payment consists of an amount and payment typeHints 1. All fields should be private. 2. The PaymentType class should be an enum class with values: CASH, DEBIT_CARD, CREDIT_CARD, CHECK 3. Payment type information should not print the enum directly 4. Use final to store the transaction for each receipt. 5. Output: A. The values for subtotal, tax, total, and payment information are all aligned. You can achieve this by using the tab character '\t' in your Strings. The item lines do not need to be aligned. B.
