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.

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your way home, you travel at an average r
kenny6666 [7]

<u><em>Answer:</em></u>

14 miles

<u><em>Explanation:</em></u>

<u>The relation that will be used to solve this problem is:</u>

Distance = Velocity*Time

<u>which can be rewritten as:</u>

Time = \frac{Distance}{Velocity}

<u>Assume that:</u>

Distance from your house to your friend's house is d

Time taken from your house to your friend's house is t₁

Time taken from your friends house to your house is t₂

<u>1- From your house to your friend's house:</u>

Average rate = 35 miles/hour

<u>Therefore:</u>

t_{1} = \frac{d}{35}

<u>2- From your friend's house to your house:</u>

Average rate = 40 miles per hour

<u>Therefore:</u>

t_{2} = \frac{d}{40}

<u>3- Round trip:</u>

We know that the round trip took 45 minutes which is equivalent to 0.75 hours

<u>This means that:</u>

t₁ + t₂ = 0.75 hours

\frac{d}{35}+\frac{d}{40}=0.75\\ \\\frac{40d + 35d}{1400}=0.75\\  \\\frac{75d}{1400}=0.75\\  \\ 1050 = 75d\\ d=14 miles

Hope this helps :)
