Answer:
- 2
Step-by-step explanation:
3 ( x + 5 ) = 9
x + 5 = 9 / 3
x + 5 = 3
x = 3 - 5
x = - 2
Answer:
(2, -3)
Step-by-step explanation:
These are the steps I used:
(6x+2y=6) x3 -> 18x+6y=18
(7x+3y=5) x2 -> 14x+6y=10
When you subtract the equations you get:
4x=8
x=2
Since the
density =mass /volume
if volume is constant we can rewrite the density equation as
volume=mass / density
since volume is just a constant
c*density=mass
where c is some constant that denotes the constant volume
mass and density will be proportional to each other or in other words will be have exactly in the same way if one increase the other will increase if one decreases the other will decrease if one stays constant the other will stay constant
only the fourth choice satisfies the proportionality condition so it must be the correct choice
Answer:
V = 3216.9 
Step-by-step explanation:
Volume of a cylinder = π 
h
We are given diameter, 16cm, and half of it is the radius
r = 8cm
h = 19cm
Substitute the values into the equation
V = π * 
* 19
V = 3216.9
Answer:
0
