Okay, let's do this~
we want v isolated on one side so let's bring w over through subtraction
now we have 5/9v=z-w
now, to get rid of that fraction attached to v, we will multiply it's reciprocal on both sides.
*the reciprocal of 5/9 is 9/5
(5/9) x (9/5) cancel each other leaving v isolated to the left
the other side should look like this 9/5(z-w)
now we put both parts together to end up with:
v= 9/5(z-w)
there you go! :D
Answer:
No you can't because just like multiplication, you cant divide anything by zero.
Step-by-step explanation:
You must evaluate the function f first. Division by 0 is undefined.
Therefore, The composition cannot be evaluated.
Answer:
They encircle the planet
times.
Step-by-step explanation:
Consider the provided information.
We have 2.5 mole of dust particles and the Avogadro's number is 
Thus, the number of dust particles is:

Diameter of a dust particles is 10μm and the circumference of earth is 40,076 km.
Convert the measurement in meters.
Diameter: 
If we line up the particles the distance they could cover is:

Circumference in meters:

Therefore,

Hence, they encircle the planet
times.
Answer:
Laura 32
Kelly 17 )
Tia 34
Step-by-step explanation:
L+ (L-15) + 2(L-15) = 83
4L - 45 = 83
4 L = 128
L = 32
Laura 32
Kelly 17 (32-15)
Tia 34 (2*17)
32+17+34 = 83
The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
