Answer:

38 units

Step-by-step explanation:

VS = TS

39 = 6x – 3

39 + 3 = 6x

42 = 6x

X = 7  

TV = 2(VR)

TV = 2 ( 2(7) + 5)

TV = 38 units

Brainiest please?

What is the value of x?<br> 21<br> 24<br> 32<br> 44
VMariaS [17]

Answer:

x = 21

Step-by-step explanation:

Because GJ is a diameter, the angle K is a right angle (90 degrees).

Sam wanted to buy candy for all of his friends to share at lunch. One pound of chocolates cost $6.95, but Sim only needs 0.6 of
OLga [1]

Answer:

The answer to your question is cost of 0.6 pound of candy $4.17

Step-by-step explanation:

Data

1 pound of candy = $6.95

only 0.6 pounds

final cost = ?

Process

1.- Use proportions to find the cost of 0.6 pounds of candy

               1 pound of candy -------------- $6.95

               0.6 pound of candy ----------   x

2.- Use cross multiplication

                 x = (0.6 x 6.95) / 1

3.- Simplification and result

                 x = $ 4.17

Solve the following system of equations for all three variables.
xz_007 [3.2K]

Answer:

Step-by-step explanation:

-2x + 3y – 4z = 8    ----------------(I)

5x – 3y + 5z = -8    -----------------(II)

7x – 3y + 3z = 8 ------------------(III)

Add equation (I) & (II) and thus y will be eliminated

(I)        -2x + 3y – 4z = 8

(II)        <u>5x – 3y + 5z = -8</u>    {Add}

           3x          + z  = 0   ------------------------(A)

Multiply equation (II) by (-1) and then add with equation (III). Thus y will be eliminated.

(II) * (-1)         -5x + 3y - 5z = +8

                     <u>7x – 3y + 3z = 8</u>   {Add}

                     2x         -2z   = 16   ---------------(B)

Multiply equation (A) by 2 and then add. Thus z will be eliminated and we will get the value of x

(A) * 2          6x + 2z = 0

(B)                 <u>2x - 2z  = 16</u>   {Add}

                     8x         = 16

Divide both sides by 8

                             x = 16/8

                          x = 2

Plugin x = 2 in equation (A)

3x + z = 0

3*2 + z = 0

 6 + z = 0

       z = -6

Plug in x = 2 and z  = - 6 in equation (I)

-2x +3y - 4z = 8

-2*2 + 3y - 4*(-6) = 8

-4 + 3y + 24 = 8

     3y   + 20 = 8

               3y = 8 - 20

               3y = -12

                 y = -12/3

y = -4
