Step-by-step explanation:

The statement in the above question is True.

Sum of three prime numbers (other than two) is always odd.

Going by Christian Goldbach number theory ,

Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .

Lets take an example,

3 + 3 + 5 = 11
3 + 5 + 5 = 13
5 + 5 + 7 = 17

Later on in 2013 the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.

seropon [69]

So, you want to do the operations on both sides.
5/4 (x-5)=-6 becomes
x-5= -6/(5/4)
becomes
x= -6/(5/4)+5

and x=0.2
Hope this helped!

AVprozaik [17]

Answer: C. Sesame oil freezes at a lower temperature than peanut oil because −6.2 °C < 3.1 °C

Step-by-step explanation:

Given that:

Freezing point of sesame oil = - 6.2°C

Freezing point of peanut oil = 3.1°C

Comparing the two temperatures :

Freezing(when a substance turns to solid) usually occurs at low temperatures. The temperature of sesame oil(-6 2°C) is lower than that of peanut oil(3.1°C).

Hence, it can be concluded that Sesame oil freezes at lower temperature than peanut oil.

Mathematically,

-6.2°C < 3.1°C

Find the measure of unlabeled angle in the quadrilateral

Tpy6a [65]

Answer:

x=140

Step-by-step explanation:

A quadralterial interior angles sum up to 360. We are given three angles and need to find the missing angle.

Let x, represent the missing angle.

$60 + 55 + 105 + x = 360$

$220 + x = 360$

$x = 140$

Suppose that a rectangle has an area of 54 square meters. Express the perimeter P as a function of the length x of one of the si

Lapatulllka [165]

Answer:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Step-by-step explanation:

The area of the rectangle can be written as:

$A = x*h$

here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.

$54 = x*h$

The perimeter of a rectangle can be written as:

$P = 2x+2h$

To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.

$54 = x*h$

$h=\dfrac{54}{x}$
