How do I solve -6/5-2/3v+4/15+1/3v

Hello! Welcome to Brainly!

In evaluating -6/5-2/3v+4/15+1/3v , we must apply PEMDAS (rules for order of operations). Here, we must perform division first, and only then add and/or subtract.

Combining the terms that involve division:

-6/5 + 4/15. The LCD here is 15, so we have -18/15 + 4/15 = -14/15.

Combining those terms that involve the variable v:

(-2/3)v + (1/3)v = (-1/3)v

Combining these two different types of sums:

14/15 - (1/3)v (answer)

solve: -6 / 5 - 2 / 3v + 4 / 15 + 1 / 3v =====> -1 / 3v + -14 / 15


-6 / 5 - 2 / 3v + 4 / 15 + 1 / 3v

= -6 / 5 + -2 / 3v + 4 / 15 + 1 / 3v


Combine Like Terms:

-6 / 5 + 2 / 3v + 4 / 15 + 1 / 3v

( -2 / 3v + 1 / 3v ) + ( -6 / 5 + 4 /15 )

-1 /3v + -14 / 15


Answer: -1 / 3v + -14 / 15

5. How many ways are there to choose seven cards from a deck of 52?
Fiesta28 [93]

Answer:

674,274,182,400

Step-by-step explanation:

In this particular situation, the first card can be chosen in 52 ways. The second card can be chose in 51 (because when you chose the first card, there were 51 left), you keep doing that seven times

So, 52*51*50*49*48*47*46

Hope this helps.

Base angle of an isosceles triangle is 42 degree,find the third angle?
IceJOKER [234]

Answer:

96°

Step-by-step explanation:

the base angles of an isosceles are congruent , both 42°

Then the third angle = 180° - 42° - 42° = 180° - 84° = 96°

The coordinates of the vertices of quadrilateral DEFG are D(−2, 5) , E(2, 4) , F(0, 0) , and G(−4, 1) .
daser333 [38]

Answer: The correct option is a.Quadrilateral DEFG is a rhombus because opposite sides are parallel and all four sides have the same length.

Explanation:

It is given that  coordinates of the vertices of quadrilateral DEFG are D(−2, 5) , E(2, 4) , F(0, 0) , and G(−4, 1) .

The distance formula for two points is given below,

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

DE=\sqrt{(2+2)^2+(4-5)^2}=\sqrt{17}

EF=\sqrt{(0-2)^2+(0-4)^2}=\sqrt{20}

FG=\sqrt{(-4-0)^2+(1-0)^2}=\sqrt{17}

DG=\sqrt{(-4+2)^2+(1-5)^2}=\sqrt{20}

Slope formula,

m=\frac{y_2-y_1}{x_2-x_1}

Slope of DE,

m_1=\frac{4-5}{2+2}= \frac{-1}{4}

Slope of EF,

m_2=\frac{0-4}{0-2}= 2

Slope of FG,

m_3=\frac{1-0}{-4-0}= \frac{-1}{4}

Slope of DG,

m_4=\frac{1-5}{-4+2}= 2

The slope of opposite sides are equal, it means the opposite sides are parallel.

All four sides do not have the same length. It means it is not a rhombus.

From the figure it is noticed that the opposite sides are parallel.

Therefore, the correct option is a.Quadrilateral DEFG is a rhombus because opposite sides are parallel and all four sides have the same length.
