Evaluating functions
spayn [35]

(-1/4)x + 2 = 8

Multiply all terms by 4.

(-1)x + 8 = 32

Simplify.

-x + 8 = 32

Subtract 8 from both sides.

-x = 24

Multiply both sides by -1.

x = -24.

<h3>The value of x is equal to -24.</h3>

-1/4(-24) + 2 = 8

artcher [175]
Since there are 8 but the last comedian will always perform last the amount of comedians you have to take into account in 7. To calculate the amount of combinations use 7! which is 5040. So there are 5040 different ways the comedians could be scheduled.

A recipe for nut bread calls for 1/4 cup of walnuts and 2/6 cup
Hitman42 [59]

Answer:

\sf Total \ amount \ of \ walnuts \ and \ pecans \ needed = \dfrac{7}{12}

Step-by-step explanation:

<h3>Fraction addition:</h3>

    \sf Amount \ of \ walnut \ needed = \dfrac{1}{4}

    \sf Amount \ of \ pecans \ needed =\dfrac{2}{6} =\dfrac{1}{3}

To find the total amount of walnut and pecans, we have to add the fractions.

  • Find the LCM of the denominators.
  • Find equivalent fractions using the LCM
  • Now, add the fractions

LCM of 4 & 3 = 12

Equivalent fractions:

      \sf \dfrac{1}{4}=\dfrac{1*3}{4*3}=\dfrac{3}{12}\\\\\dfrac{1}{3}=\dfrac{1*4}{3*4}=\dfrac{4}{12}

Now, add

   \sf \dfrac{3}{12}+\dfrac{4}{12}=\dfrac{3+4}{12}

                  \sf = \dfrac{7}{12}
