Given:

4x + 7 = 23

Let's solve for x.

First Step:

Subtract 7 from both sides

4x + 7 - 7 = 23 - 7

4x = 16

Next Step:

DIvide both sides by 4

\begin{gathered} \frac{4x}{4}=\frac{16}{4} \\  \\ x\text{ = 4} \end{gathered}

ANSWER:

x = 4

Parts of an algebraic expression separated by plus or minus signs are
goblinko [34]

Answer:  called tthe term of an algebraic expression.

<h3 /><h3>Step-by-step explanation: We know an algebraic expression is a collection or combination of constant and variables of one or more terms, which are separated by the fundamental operations (+, –, × and ÷).</h3><h3 /><h3>Some of the examples of algebraic expression are 7b + 5m, 5x + 3y + 10, 5x/y + 3, x + y + z, etc.</h3><h3>Terms of an algebraic expression:</h3><h3>Each part of an algebraic expression which are separated by plus sign (+) or minus sign (-) is called the term of an algebraic expression. It’s important to remember that the division sign (÷) or multiplication sign (×) does not separate the terms of an algebraic expression.</h3>

Examples of algebraic expressions and their terms:

(i)  x + 10

We observe that the number of terms used in the expression x + 10 is 2. The terms are x and 10.

(ii)  5m + 2n - 7

We observe that the number of terms used in the expression 5m + 2n – 7 is 3. The terms are 5m, 2n and 7.

(iii)  3a/b

We observe that the number of term used in the expression 3a/b is 1. The term is 3a/b.

(iv) 3xy + 7xz + 2yz - 6

We observe that the number of terms used in the expression 3xy + 7xz + 2yz - 6 is 4. The terms are 3xy, 7xz, 2yz and 6.

)  2abc + 1

We observe that the number of terms used in the expression 2abc + 1 is 2. The terms are 2abc and 1.

Therefore, the algebraic expressions are either simple or compound.

(i) Simple algebraic expressions consist of one term.

(ii) Compound algebraic expressions consist of two or more terms.

Which of the followingis multiplicative of -a? (-1/a a 1 1/a)​
Elodia [21]

Given:

The given value is -a.

To find:

The multiplicative inverse of -a.

Solution:

We know that y is the multiplicative interval of x if xy=1.

Let x be the multiplicative inverse of the given value -a. Then,

(-a)\times x=1

Divide both sides by -a.

x=\dfrac{1}{-a}

x=-\dfrac{1}{a}

Therefore, the multiplicative inverse of -a is -\dfrac{1}{a}. Hence the correct option is A.
