Step-by-step explanation:
taking that blank as x
5/2 -x = 1/3
the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3
so the equation will become 5/2-1/3=x
solving the fraction then gives 13/6 or 2.17 as the value of x
She makes $300, 50 multiplied by 6 equals 300
The absolute value of a number is its distance from 0. The absolute value of -4 is 4, the absolute value of 4 is 4.
-4 + 4 is 0, so she's right there; but 4, + its absolute value, 4, is 8. This means that Kayla is incorrect.
<span>On a certain survey it says:
12 out 15 people in the United States prefer eating at the restaurant rather
than home.
To know how many percent is this.
=> 12 / 15
=> 0.8 which is also 80%
Now, the 80% of the those people in the
survey is 400.
Find the total number of people who took
the survey.
Since we already have the 80%, we need to find the number of 20%
=> 400 x 20%
=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey

Answer: The volume of given substance is
.
Step-by-step explanation:
Given: Density = 10.7 ![g/cm^{3}](https://tex.z-dn.net/?f=g%2Fcm%5E%7B3%7D)
Mass = 23.54 g
Density of a substance is the mass of substance divided by its volume.
Mathematically, ![Density = \frac{mass}{volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7Bmass%7D%7Bvolume%7D)
Substitute the values into above formula to calculate volume as follows.
![Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7Bmass%7D%7Bvolume%7D%5C%5C10.7%20g%2Fcm%5E%7B3%7D%20%3D%20%5Cfrac%7B23.54%20g%7D%7Bvolume%7D%5C%5Cvolume%20%3D%20%5Cfrac%7B23.54%20g%7D%7B10.7%20g%2Fcm%5E%7B3%7D%7D%5C%5C%3D%202.2%20cm%5E%7B3%7D)
Thus, we can conclude that the volume of given substance is
.
