Which logarithmic equation is equivalent to the exponential equation below 9x = 27

You are asking to write 9^x=27 in logaritmic form

Remember that log_{a}(b)=c translates to a^c=b

So therefore 9^x=27 translates to log_{9}(27)=x

-98 = 7t<br> What does t equal
pentagon [3]

Answer:

t = -14

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

-98 = 7t

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. Divide 7 on both sides:                    -14 = t
  2. Rewrite:                                             t = -14

<u>Step 3: Check</u>

<em>Plug in t into the original equation to verify it's a solution.</em>

  1. Substitute in <em>t</em>:                     -98 = 7(-14)
  2. Multiply:                               -98 = -98

Here we see that -98 is equal to -98.

∴ t = -14 is the solution to the equation.

One of the same side angles of two parallel lines is 20° smaller than the other one. Find all angles.
KiRa [710]
Hello.

First, draw a picture of two parallel lines and a transversal.
Find the two same side angles, either the same side interior or the same side exterior.
We do not know the measurement of the angle, so we'll label it x.
The second angle is 20° smaller than the other one so we'll label is x-20

Same side angles are supplementary. Meaning that they add up to 180°

Next, make an equation.
1st angle + 2nd angle = 180°
Now substitute the first and second angle to x and x-20
The substituted equation should now look like this.
x+x-20=180
solve it and you'll get...
x=100

But we're not done.

The angle labeled x is 100°
The other one is x-20
And since x=100, the second angle is 100-20=80°
Now use linear pairs, more same side angles, vertical angles, alternate angles, and linear pairs, to label the rest. Remember that each angle is either 100° or 80°.

Hope this helped!
