Answer:
3
Step-by-step explanation:
1: Turn the mixed fraction into improper.
2: Multiply 3/5 to each side
3: The you get x = 3
You need to multiply the fraction instead of division because multiplying by the reciprocal is the same as dividing the normal fraction.
Essentially, you're going to want to reverse the steps on x in order to isolate it from the rest of the variables. To do this, perform inverse operations on x. The first one of these is the multiplication of x and m, so divide both sides by m to cancel m out on the right side. Now we have y/m = x + b. The final thing to do in order to isolate x is to subtract b from both sides. This yields us y/m - b = x. This can be rearranged into x = y/m - b, which should be your answer.
You need to add a -1
We can find this by setting up the equation like so
x + (-6) + 12 + 15 / 4 = 5
x + 21 = 20
x = 20 -21
x = -1
Now if we insert -1 where x is located in the equation, you will get a means of 5
Answer:
![d=0.364\ g/cm^3](https://tex.z-dn.net/?f=d%3D0.364%5C%20g%2Fcm%5E3)
Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,
![\rho=\dfrac{m}{V}\\\\=\dfrac{36.4\ g}{100\ cm^3}\\\\=0.364\ g/cm^3](https://tex.z-dn.net/?f=%5Crho%3D%5Cdfrac%7Bm%7D%7BV%7D%5C%5C%5C%5C%3D%5Cdfrac%7B36.4%5C%20g%7D%7B100%5C%20cm%5E3%7D%5C%5C%5C%5C%3D0.364%5C%20g%2Fcm%5E3)
So, the density of benzene is

Answer: 124
Step-by-step explanation:
20 + 52*2 = 20 + 104
20 + 104 = 124
