Answer:

A) x= -3

Step-by-step explanation:

5+6x=2x-7

add 7 to both sides

12+6x=2x

subtract 6x from both sides

12=-4x

divide 4x from both sides

-3=x

PtichkaEL [24]

Answer:

1. B

2.C

Step-by-step explanation:

A plot of land in the shape of a vertical ellipse. The equation of the ellipse is

\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1.

If the foci are 8 feet from the center, then c=8.

If the plot of land is 34 feet across the vertical axis, then 2b=34\Rightarrow b=17.

Use formula c=\sqrt{b^2-a^2} (because ellipse is vertical, then b>a) to find a:

8=\sqrt{17^2-a^2}\Rightarrow a^2=289-64=225,\ a=15.

Then  the plot of land is 2a=30 ft across the other axis.

If b>a, the eccentricity of the ellipse is

e=\dfrac{c}{b}=\dfrac{8}{17}\approx 0.471.

Ted is making trail mix for a party .He mixes 1/1/2cups of nuts,1/4 cup of raisins,and 1/4 cup of pretzels.How many cups of pret
balandron [24]

Answer:

1.875 or 1\frac{7}{8} cups of pretzel

Step-by-step explanation:

The number of cups needed is equivalent to the probability of pretzel in the mix times the number of cups in the mix.

-The probability of pretzel is :

P(pretzel)=\frac{0.2}{0.25+0.25+1.5}\\\\=0.125

We multiply this probability by the number of cups of the mix:

=P(pretzel)\times (mix \ cups)\\\\=0.125\times 15\\\\=1.875 \ or \ 1\frac{7}{8}

Hence, 1.875 or 1/7/8 cups of pretzel is needed.
