Answer:

6. Z= -11

7. N= 15.25

Step-by-step explanation:

6. Subtract 10 from each side to get Z+3= -8

Then Subtract 3 from each side to get Z= -11

7. Subtract 4 from each side to get 3/4 n= 16

Then Subtract 3/4 to get N= 15.25

z + 3/10 = 2

z+3 = 2 × 10

z +3 = 20

z = 20-3

z = 17

(3/4)n + 4 = 20

n + 4 = 20 ÷ 3/4

n + 4 = 20 × 4/3

n + 4 = 80/3

n = 80/3 -4

n = 80-12/3

n = 68/3

the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of

marin [14]

It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3

Answer:

Option (4)

Step-by-step explanation:

Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).

Slope of XY ( $m_{1}$ ) = $\frac{y-y'}{x-x'}$
