Answer:

  C.  Matrix C

Step-by-step explanation:

The usual form for an augmented matrix representation of a system of linear equations has the variable coefficients listed in a square matrix with an additional column at the right containing the constants in the standard-form equations. This is illustrated in Matrix C.

__

The variables in the equations are usually left out of the matrix. That is, the system of equations AX= B is usually represented by the augmented matrix A|B, rather than (AX)|B. Thus "Matrix B" is not the best choice.

How would you use estimation to evaluate this expression 10.2 x [(2x3.7)+8]
Goryan [66]
Round off the decimals to a sensible number. So 3.7 would be 4 and 10.2 would be 10. In this case, it would be (2 × 4 + 8) × 10 which is 160.

Solve 4(x + 2) = 20
KiRa [710]

Answer:

x = 3

Explanation:

\sf 4(x + 2) = 20

\sf 4x + 8 = 20

\sf 4x = 20 - 8

\sf 4x = 12

\sf x = \frac{12}{4}

\sf x = 3

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3

If you use/make a number line, then you will see that the answer is -18 or a. When using a number line, negative = ← and positive = →.
