Answer:

The answer is B. Warm air rises, and cool air sinks.

Step-by-step explanation:

During atmospheric convection, heat is transferred as a result of heated air (which is lighter and less dense) rising, and cool air (which is heavier and more dense) sinking beneath the heated air: this movement of heated and cool air produces patterns of circulation known as atmospheric convection currents.

Solve the proportions:

IRINA_888 [86]

<u>Answer:</u>

6. 6.75
7. 27
8. 92/17
9. 49

<u>Step-by-step explanation:</u>

<u>- Question 6 -</u>

9/16 = x/12
=> 16x = 12 x 9
=> 16x = 108
=> x = 6.75

Hence, <u>the value of x in this proportion is 6.75.</u>

<u>- Question 7 -</u>

-3 + x/18 = 12/9
=> -3/18 + x/18 = 4/3
=> x/18 = 4/3 + 1/6
=> x/18 = 8/6 + 1/6
=> x/18 = 9/6
=> x = 9/6 x 18
=> x = 27

Hence, <u>the value of x is 27</u>

<u>- Question 8 -</u>

17/15 = 10/2x - 2

=> 17(2x - 2) = 150

=> 34x - 34 = 150

=> 34x = 184

=> x = 184/34

=> x = 92/17

Hence, <u>the value of x is 92/17</u>

<u>- Question 9 -</u>

x - 16/x + 6 = 3/5
=> 5(x - 16) = 3(x + 6)
=> 5x - 80 = 3x + 18
=> 2x = 98
=> x = 49

Hence, <u>the value of x is 49.</u>

The expression on the left side of an equation is shown below. If the equation has an infinite number of solutions, which expres

chubhunter [2.5K]

The answer is D. -2x+5.

If we simplify the left side of the equation first given, we come to the expression -2x-10.

If we solve for D., we get the same results. Thus, because an equation with all the same variable terms and constants have infinite solutions, the answer is D.

Hope this helps!

Please Answer Quick 70 Points !

Kipish [7]

Answer:

The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

Step-by-step explanation:

we have

$2x-y=-5$ -----> First equation

$x+3y=22$ -----> Second equation

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (1,7)

The ordered pair (7,19) lie on the first line, so is a solution of the first equation

see the attached figure

<u><em>Verify each statement</em></u>

case 1) The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The statement is true

case 2) The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true

The statement is false, because the ordered pair (7,19) not lie on the second line

case 3) The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

The statement is true

case 4) The ordered pair (7, 19) is a solution to the system because it makes both equations true

The statement is false,because it makes only the first equation true
