Answer:

The solved given expression is

\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}

Step-by-step explanation:

Given expression is \frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}

To solve the given expression :

\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}

=\frac{-4+4+2x}{7}-14x

=\frac{0+2x}{7}-14x

=\frac{2x}{7}-14x

=\frac{2x-14x(7)}{7}

=\frac{2x-98x}{7}

=\frac{-96x}{7}

Therefore \frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}

Therefore the solved given expression is

\frac{-4}{7}+\frac{2}{7}x-14x+\frac{4}{7}=\frac{-96x}{7}

Step-by-step explanation:

15) 13x = 130 x = 10

16) 16x+2+43x+1 = 180 59 x = 177 x = 3

17) 29x+3+31x-3 = 180 60x = 180 x = 3

18) 16x -5 + -5 + 22x = 180 38x = 190 x = 5

What is the answer to > solve 4cos (theta/3) -2 = 0, over [0, 4pi)
Vesna [10]

Hello from MrBillDoesMath!

Answer:  

@ =   pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)


Discussion:

Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)

where

4cos(@) - 2 = 0.                Adding 2 to both sides

4 cos(@) - 2 +2 = 2  =>

4 cos(@) = 2                     Divide both sides by 4

cos(@) = 2/4 = 0.5


This implies that @ =   pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)


Thank you,

MrB

The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its d
Vlad1618 [11]

Hey there! I'm happy to help!

Let's call the length and width L and W respectively.

L=2W+8

2W+2L=124

We plug our value of L into the second equation and solve for W.

2W+2(2W+8)=124

We undo the parentheses with the distributive property.

2W+4W+16=124

Combine like terms.

6W+16=124

Subtract 16 from both sides.

6W=108

Divide both sides by 6.

W=18

We plug this W value into the first equation to solve for L.

L=2(18)+8

L=36+8

L=44

So, the length is 44 feet and the width is 18 feet.

Have a wonderful day! :D
