6x +30 -3x +6 =12x +18
3x +36 =12x +18
3x-12x = 18 -36
-9x = -18 | -1
9x =18
x= 18/9
x=2
Answer:
1)The mass of water increases.
2) Freezing point of water decreases.
3) buoyancy of objects in the water increases.
Step-by-step explanation:
Salinity in the oceanic water is attributed by the water coming from other sources like rivers carrying rocks and soil containing salt. Salinity decreases the temperature of water, making it cold and more denser. The cold water settles at the bottom of the ocean. It flows across the oceanic basins as slow currents. The objects being less in density flows over the surface of water. Hence,buoyancy of objects in water increases.

Answer:
a: (4,4) B:(10,6) C:(0,2) D: over 12 E: over 3, up 2 F: up 7
There are 3,300 different ways to select the committee.
First, we need to determine the total number of ways the 6 members can be selected.
For the chair and vice chair, it would be 5 x 4 = 20, but then that has to be divided by 2. (Because the order doesn't matter)
20 / 2 = 10
For the rest, it would be 11 x 10 x 9 x 8 = 7920, but again divide it by 4! because the order doesn't matter.
7920 / 24 = 330
To find the total ways for both, multiply 10 by 330 to get 3300.
So,
The length is always 1.5 times the width.
l = 1.5w
lw = 24
lw = 54
lw = 96
Or, we could put it this way:
1.5w(w) = 24
1.5w(w) = 54
1.5w(w) = 96
So,
1.5w^2=24
1.5w^2=54
1.5w^2=96
Dividing both sides by 1.5, we get:
w^2 = 16
w^2 = 36
w^2 = 64
And solving for the only logical dimension, we get:
w = 4
w = 6
w = 8
And their corresponding lengths:
l = 1.5(4) = 6
l = 1.5(6) = 9
l = 1.5(8) = 12
So a few lengths could be:
(l,w)
(6,4)
(9,6)
(12,8)
Of course, there are infinite solutions.
