3 consecutive odd integers such that the sum of twice the first and three times the second is 55 more than twice the third

den301095 [7]

Answer:

Consecutive odd integers are 19 , 21 & 23

Step-by-step explanation:

Let the first 3 consecutive odd intergers be x , (x + 2) and (x + 4).

According to the question,

$2x + 3(x + 2) = 2(x + 4) + 55$

$= > 2x + 3x + 6 = 2x + 8 + 55$

Eliminating 2x from both the sides,

$= > 3x + 6 = 63$

$= > 3x = 63 - 6 = 57$

$= > x = \frac{57}{3} = 19$

So, the consecutive odd integers are = 19 , 21 & 23.

A beach ball has a mass of 5 g and a volume of 20 cm3. What is the object's density? A. 4 g/cm3 B. 100 g/cm3 C. 0.25 D. g/cm3 4

Triss [41]

<h2>Hello!</h2>

The answer is:

C. $0.25\frac{g}{cm^{3} }$

<h2>Why?</h2>

The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:

$Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}$

So, the correct options is C. $0.25\frac{g}{cm^{3} }$

Have a nice day!
