This is because it is 3/10
The 10 is 100%
He drank 3/10 of it
Divide 100 by 3
You get 30
Your answer is 30%

Answer:

<em></em>

  • <em>    Variable</em>
  • <em>    Variable expression</em>
  • <em>    Number</em>

Explanation:

A <em>literal equation</em> contains numbers, letters, and signs.

The letters represent variables, the numbers are constants, and the sign express relations, like equal (=), less than (<), and greater than (>).

You use the signs to make equations or inequalities.

Algebra is the use of mathematical rules applied to literal expressions. You can add, subtract, multiply and divide literal, expressions, like in arithmetic,  following some rules.

<em>To rewritte a literal equation in terms of a specific variable</em>, you may need to <em>divide by</em>  <em>another variable, a variable expression, or a number</em>, but never by an inequality sign.

Here you have one example for each case:

<u>1. Dividing by another variable.</u>

     x^2y^5=100\\\\\\ \dfrac{x^2y^5}{y^5}=\dfrac{100}{y^5}\\ \\ \\ x^2=\dfrac{100}{y^5}

<u>  2. Dividing by a variable expression.</u>

      x^2(z^3+y^5)=100\\\\\\ \dfrac{x^2(z^3+y^5)}{(z^3+y^5)}=\dfrac{100}{(z^3+y^5)}\\ \\ \\ x^2=\dfrac{100}{(z^3+y^5)}

<u>3. Dividing by a number:</u>

   

      200x^2=100\\\\\\ \dfrac{200x^2}{200}=\dfrac{100}{200}\\ \\ \\ x^2=\dfrac{100}{200}\\ \\ \\ x^2=0.5

As said above,  you cannot divide by an inequality sign.

Dominic is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The monthly fe
insens350 [35]

The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

<h3>Equation</h3>

There are three basic types of equation in mathematics. Namely:

  • Linear equations
  • Quadratic equations
  • Simultaneous equations

  • Monthly fee = $50
  • One-time joining fee = $150
  • Total cost = C
  • Number of months = t

C = 150 + 50t

Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

2.4 + 5.4q – 4.5q + 3.6<br><br> a.6+1.1q<br> b.9.9q+6<br> c.0.9q+6<br> d.9.9q-6
Yuri [45]
You have to add the same kind of terms, in this case the ones that have a variable (5.4q and -4.5q) and the ones that don't (2.4 and 3.6), like this:

(5.4q - 4.5q) + (2.4 + 3.6) = 0.9q + 6

The answer is c. 0.9 +6
