In the system -12c+3d=6 and -3c+6d=-9, which expression could you use for substitution?. A. d=-1/2c-3/2. B.c=-2d+3. C.c=1/4d-1/2
nikdorinn [45]
The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6  / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6  /  : 12  ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2

HELP 1/7z+2=-6/7z what’s the solution set please send help I’m suffocating under homework
Snezhnost [94]

Isolate the z. Note the equal sign. Subtract 1/7z to both sides

1/7z (-1/7z) + 2 = -6/7z (-1/7z)

2 = -6/7z - 1/7z

Simplify. Combine like terms

2 = -7/7z

2 = -1z

Isolate the z. Divide -1 from both sides

(2)/-1 = (-1z)/-1

z = 2/-1

z = -2

-2 is your answer

hope this helps

Answer:

b) 336 cm³

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Geometry:</u>

  • Volume of a Rectangular Prism: V = lwh

Step-by-step explanation:

<u>Step 1: Define</u>

l = 4 cm

w = 6 cm

h = 14 cm

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute:                    V = (4 cm)(6 cm)(14 cm)
  2. Multiply:                        V = (24 cm²)(14 cm)
  3. Multiply:                        V = 336 cm³

And we have our final answer!
