Answer: 6 days.

Step-by-step explanation:

Keep subtracting 2/3 from 4 until you have no gummy bears left. You woukd have to subtract 6 times to get to 0, so it would have to take 6 days.

Solve: 2cos(x)-square root 3=0 for 0 less than x less than 2 pi

Leona [35]

Answer:

The general solution of $cos x = cos(\frac{\pi }{6})$ is

x = 2nπ± $\frac{\pi }{6}$

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Step-by-step explanation:

Explanation:-

Given equation is

$2cosx-\sqrt{3} =0 for 0$

$2cosx =\sqrt{3}$

Dividing '2' on both sides, we get

$cos x =\frac{\sqrt{3} }{2}$

$cos x = cos(\frac{\pi }{6})$

<em>General solution of cos θ = cos ∝ is θ = 2nπ±∝</em>

<em>Now The general solution of </em> $cos x = cos(\frac{\pi }{6})$ <em> is </em>

<em> x = 2nπ±</em> $\frac{\pi }{6}$ <em></em>

put n=0

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Put n=1

$x = 2\pi +\frac{\pi }{6} = \frac{13\pi }{6}$

$x = 2\pi -\frac{\pi }{6} = \frac{11\pi }{6}$

put n=2

$x = 4\pi +\frac{\pi }{6} = \frac{25\pi }{6}$

$x = 4\pi -\frac{\pi }{6} = \frac{23\pi }{6}$

And so on

But given 0 < x< 2π

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

I want help with this equation -1 + x = 8x - 8

Ilya [14]

Answer:

x=1

Step-by-step explanation:

To solve for x, we need to get x alone on one side of the equation.

Add one to each side of the equation. Subtract 8x from each side of the equation. Divide both sides by -7. You should get 1 as the answer.

$-1+x=8x-8\\x=8x-7\\-7x=-7\\x=1$

At another school they sell a different brand of gift wrap which costs $2 per package and cards for $5 per package. Your friends

zhenek [66]

Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55 ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards

695/2=347 packages without cards

SO

139 packages with card

347 packages without card
