Answer:
x=2
Step-by-step explanation:
14x+3=31
Step 1: Subtract 3 from both sides.
14x+3−3=31−3
14x=28
Step 2: Divide both sides by 14.
14x/14=28/14
x=2
Answer:
![\rho = \frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D)
And if we solve for m we got:
![m = \rho V](https://tex.z-dn.net/?f=%20m%20%3D%20%5Crho%20V)
And replacing we got:
![m = 0.1755 \frac{Kg}{m^3} * 2600 m^3 = 456.3 Kg](https://tex.z-dn.net/?f=%20m%20%3D%200.1755%20%5Cfrac%7BKg%7D%7Bm%5E3%7D%20%2A%202600%20m%5E3%20%3D%20456.3%20Kg)
And if we round to the nearest value we got 456 Kg
Step-by-step explanation:
For this problem we know the following info:
represent the volume
represent the density
We want to find the mass and we can use the following definition:
![\rho = \frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D)
And if we solve for m we got:
![m = \rho V](https://tex.z-dn.net/?f=%20m%20%3D%20%5Crho%20V)
And replacing we got:
![m = 0.1755 \frac{Kg}{m^3} * 2600 m^3 = 456.3 Kg](https://tex.z-dn.net/?f=%20m%20%3D%200.1755%20%5Cfrac%7BKg%7D%7Bm%5E3%7D%20%2A%202600%20m%5E3%20%3D%20456.3%20Kg)
And if we round to the nearest value we got 456 Kg
Answer:
She should use 1/2 cup of chocolate chips.
Step-by-step explanation:
If she uses 2 cups for 8 people, that means
2 x 4 =8
So, all you have to do is,
? x 4 = 2
0.5 x 4 = 2
0.5 = 1/2
She should use 1/2 cup of chocolate chips
When you change the radius (multiply by k), a 1D size, the circumference is multiplied by k (1D), while the area is multiplied by
![k^2](https://tex.z-dn.net/?f=k%5E2)
(2D). I hope this helps on this problem and others.
