-7w + 2(w + 8) = -24 Can you help me find w?

1 answer:

6 0

-7w + 2(w + 8) = -24

First, expand your equation.
$-7w + 2w + 16 = -24$
Second, add '-7w + 2w' to get '5w'.
$-5w + 16 = -24$
Third, take away '16' from both sides.
$-5w = -24 - 16$
Fourth, subtract '-24 - 16' to get '-40'.
$-5w = -40$
Fifth, divide both sides by '-5' and change it into a positive.
$w = \frac{40}{5}$
Sixth, how many times does 5 go into 40? 40 ÷ 5 = 8.
$w = 8$

Answer: w = 8

Solve by elimination:

Answer:

Ok, there's no solution because of the like term grouping

Step-by-step explanation:

For eg;2w+3x+4w will be equal to

6w+3x which is a like term grouping. So only if there are like terms, there will be a solution.

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two

Vikentia [17]

Answer:

the probability of no defects in 10 feet of steel = 0.1353

Step-by-step explanation:

GIven that:

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two.

Let consider β to be the average value for defecting

So;

β = 2

Assuming Y to be the random variable which signifies the anticipated number of defects in a 10-foot segment of this roll.

Thus, y follows a poisson distribution as number of defect is infinite with the average value of β = 2

i.e

$Y \sim P( \beta = 2)$

the probability mass function can be represented as follows:

$\mathtt{P(y) = \dfrac{e^{- \beta} \ \beta^ \ y}{y!}}$

where;

y = 0,1,2,3 ...

Hence, the probability of no defects in 10 feet of steel

y = 0

$\mathtt{P(y =0) = \dfrac{e^{- 2} \ 2^ \ 0}{0!}}$

$\mathtt{P(y =0) = \dfrac{0.1353 \times 1}{1}}$

P(y =0) = 0.1353

What is the height of the beach sign?

bagirrra123 [75]

To find the height of this umbrella you need to use the tangent function.

$tan 45 = \frac{8}{x}$
$(tan 45)(x) = 8
$
$x = \frac{8}{tan 45}$
$x = \frac{8}{1}$
$x = 8$

The height of the umbrella is 8.

Hope this helps :)
