If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.

Ksivusya [100]

Based on the calculations, the unknown number is equal to $\frac{-45}{7}$

Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

$21 +x$

Multiplying the result by 3:

$3\times (21+x)$

84 more than two-thirds of the unknown number:

$\frac{2x}{3} +84$

Equating the equations, we have:

$3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84$

Cross-multiplying, we have:

$43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}$

PLEASE HELP 20 POINTS!!

Harman [31]

Answer:

Step-by-step explanation:

A relation only becomes a function if each x-value only has a single y-value as the answer.

<u>Evaluating</u>

A and B cannot be the answers as each value will get 2 answers
C will also not be the answer as y² means at least 2 answers will be given
<u>D</u> is the best option as each inputted x-value will get an answer of a single y-value
