-3.75+2(-4x+6.1)-3.25

Mathematics
1 answer:
Pani-rosa [81]2 years ago
3 0

The value of x is 0.65

<u>Step-by-step explanation:</u>

This solution is given by solving the given problem using BODMAS rule.

This means that the steps to be followed to find the solution should be in the order of BODMAS rule.

B- Bracket, O- of, D- Division, M- Multiplication, A- Addition, S- Subtraction.

This rule states that the 1st operation must be done for Brackets.

⇒ -3.75+2(-4x+6.1)-3.25 = 0

⇒ -3.75 -8x + 12.2 -3.25 = 0

The addition operation should be performed next and then followed by subtraction.

⇒ -8x -7+ 12.2 = 0

<u>To find the value of x :</u>

Keeping the x term alone on one side and moving the constants on other side,

⇒ -8x = -12.2 + 7

⇒ -8x = -5.2

⇒ x = 5.2/8

⇒ x = 0.65

Two friends share 1/2 of a pineapple equally.What fraction of a whole pineapple does each friend get?
Katyanochek1 [597]
They each get 1/4.

Because since they have 1/2 they will further divide that piece in 2 so each of them will get 1/4 of the whole.

Hope this helps :)

Simplify the expression x^2+x-2/8x^2+4x/3x^2+10x+8
irina [24]

Answer:

Step-by-step explanation:

x² + x  - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1)  = (x-1)(x+2)

8x² + 4x = 4x ( 2x + 1)

3x² + 10x + 8 = 3x² + 6x + 4x + 4*2  =3x  * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal
frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)=\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)=1 - 0.99^{50}=0.395
