Answer:

Step-by-step explanation:

x= -2

2x² - 5x + 6 = 2(-2)² - 5*(-2) + 6

                  = 2*4 + 10 + 6

                   = 8 + 10 + 6

valentina_108 [34]

The <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.

Since the Hickory Stick has a selection of 3 meats and 6 vegetables, the number of ways we can select <u>one </u>meat out of 3 is ³C₁ = 3.

Also, the number of ways we can select <u>one </u>vegetable out of 6 is ⁶C₁ = 6.

So, the total number of selections of <u>one</u> meat and <u>one</u> vegetable is ³C₁ × ⁶C₁ = 3 × 6

= 18 selections

So, the <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.

5x-1/5=7/3 <br> Find The LCD That would eliminate the fractions
photoshop1234 [79]

Answer:

x=\frac{7}{15}

Step-by-step explanation:

5x-\frac{1}{5} =\frac{7}{3}

5x - \frac{3}{15}  = \frac{35}{15}

5x - \frac{3}{15}  + \frac{3}{15} = \frac{35}{15}  + \frac{3}{15}

5x=\frac{35}{15}

\frac{5x}{5} } =\frac{\frac{35}{15}}{5}

x=\frac{7}{15}
