Answer:

letters

Step-by-step explanation:

The right answer is letters

Arithmetic is a branch of mathematics that studies the numbers and the properties with them. The main properties are addition, subtraction, multiplication and division. Variables are non-constant values, so we use letters to assign a number to a variable and the operator that allows us to do this is =. For instance, if we have the variable x, we can say that this variable is equal to 4. Then:

x=4

Suppose the value of the variable changes to 5, then the new value of it is given by:

x=5

Find the solution set for 8x - 3 = 2(x - 1/2)

KiRa [710]

Answer:

x = 1/3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

8x - 3 = 2(x - 1/2)

Step 2: Solve for x

Distributive 2: 8x - 3 = 2x - 1
Subtract 2x on both sides: 6x - 3 = -1
Add 3 to both sides: 6x = 2
Divide 6 on both sides: x = 1/3

Mark all the statements that are true . A. This graph is a function whose domain is the set 3 B. This graph is a function becaus

nika2105 [10]

The statements that are true are

This graph is a function because the value of x is the same for every value of y
The equation of this line is x = 3. Options B and D

This is further explained below.

<h3>What are the statements?</h3>

Generally, A relation is considered to be a function if it can be shown that each value from the set of first components of ordered pairs is connected with precisely one value from the set of second components of ordered pairs.

In conclusion, You may also consider this in terms of the fact that there is one and only one y associated with each x.

Although it is obvious that this is not the case, the calculation for the vertical line nevertheless uses these terms.

In the lab, Keith has two solutions that contain alcohol and is mixing them with each other. He uses twice as much Solution A as

egoroff_w [7]

Answer:

Quantity of solution B required is 300 ml

Step-by-step explanation:

Let "a" be quantity of solution A required

Let "b" be quantity of solution B required

We are given Solution A is 19% alcohol and Solution B is 14% alcohol and that the resulting mixture has 156 milliliters of pure alcohol

Thus;

0.19a + 0.14b = 156 - - - (eq 1)

Also, He uses twice as much Solution A as Solution B.

Thus;

a = 2b

Putting 2b for a in eq 1 gives;

0.19(2b) + 0.14b = 156

0.38b + 0.14b = 156

0.52b = 156

b = 156/0.52

b = 300 ml

Quantity of solution B required is 300 ml

Choose the correct graph to fit the inequality x^2 - y^2 < 9

Makovka662 [10]

There is no pictures to choose the right one among tem.

However the equation could be rewritten as follows:

y=√(x²-9)

It is a HORIZONTAL parabola with the following constraint: 3=<x=<-3
