Answer:

Sureeeeeee

Step-by-step explanation:

Algebra (from Arabic: الجبر‎, romanized: al-jabr, lit. 'reunion of broken parts,[1] bonesetting[2]') is one of the broad areas of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols;[3] it is a unifying thread of almost all of mathematics.[4] It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.[5] For example, in {\displaystyle x+2=5}x+2=5 the letter {\displaystyle x}x is an unknown, but applying additive inverses can reveal its value: {\displaystyle x=3}x=3. Algebra gives methods for writing formulas and solving equations that are much clearer and easier than the older method of writing everything out in words.

The word algebra is also used in certain specialized ways. A special kind of mathematical object in abstract algebra is called an "algebra", and the word is used, for example, in the phrases linear algebra and algebraic topology.

A mathematician who does research in algebra is called an algebraist.

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Answer:

<3.

Step-by-step explanation:

Algebra In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols. it is a unifying thread of almost all of mathematics. And algebraic expression includes, a variable is an x, but they could be different signs like maybe a y, q and etc. coefficient is the main number, an operation which is the sign (+, x, - or division sign). and then the constant, which are the last number and the final number.

I don't know how to explain it but as soon as you start to do it, you'll learn what algebra is! it's not that hard it's like doing a regular problem just with a variable.

Oh yeah, sorry if this out of order but sometimes in algebra you have to figure out what the x is in some problem. Khan academy could help you learn!

hope this helps <33.

coldgirl [10]

Answer:

Step-by-step explanation:

You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.

The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:

3M + 8V = 55

The second month: 5 movies, 2 video games, $18. Translated:

5M + 2V = 18

Solve that system of equations

Simplify,write equivalent expressions. 1/6(15a+20b)
lutik1710 [3]
1/6* (15a+20b)
= 1/6* 15a + 1/6* 20b (Distributive property)
= 2.5a + 10/3*b

The final answer is 2.5a+ 10/3b

Hope this helps~

Show how to find the unit rate of oats to quinoa. Tell what the unit rate means.
Dmitry [639]

Answer:

The unit rate is 4 cups of oats per a cup of quinoa

Unit Rate is a ratio of two measurements in which the 2nd term is 1

Step-by-step explanation:

* Lets explain the meaning of unit rate

- A rate is a ratio that is used to compare different types of quantities

- A unit rate describes how many units of the first type of quantity

 corresponds to one unit of the second type of quantity

- To calculate the unit rates, we simply divide the two numbers

  in a fraction with denominator equal 1

- Ex:

# The unit rate of 50 miles per 5 hours is 50/5 = 10 miles per hour

# The unit rate of $20 dollars for 5 books is 20/4 = 5 dollars per book

∴ <u><em>Unit Rate is a ratio of two measurements in which the 2nd term is 1</em></u>

<u><em /></u>

* <em>Lets find the unit rate of oats to quinoa</em>

∵ There are 2 cups of oats

∵ There is a 1/2 cup of quinoa

∵ We need the unit rate of oats to quinoa

- Divide the quantity of oats by the quantity of quinoa

∴ 2/(1/2) ⇒ multiply up and down by 2

∴ (2 × 2)/(1/2 × 2) = 4/1

∴ <u><em>The unit rate is 4 cups of oats per a cup of quinoa</em></u>
