Answer: In the equations that you have given, we have a dependent system.

2x + y = 8 (I assumed that you meant to type y instead of 7)
6x + 3y = 24


To use Cramer's Rule, we have to take the determinant of 3 different matrices written in the problem. Taking the determinant of the coefficient matrix produces a zero.

2  1   This is the coefficient matrix.
6  3

6 - 6 = 0

Since this is 0, the rest of the work will be undefined meaning the systems are dependent (or they are the versions of the same equation).

Answer:

The given system of equation is neither inconsistent nor contains the dependent equation.

Step-by-step explanation:

Given system of equation,

2x + 7y = 8,

6x + 3y = 24,

Since, the determinant of coefficients of variables,

D=\begin{vmatrix}2 & 7 \\ 6 & 3\end{vmatrix}

=2\times 3-7\times 6

=6-42

=-36

Since, D ≠ 0,

Hence, the given system of equation is neither inconsistent nor contains the dependent equation.

The skating rink rented 218 pairs of skates during the month of April and 3 times that many in May. How many pairs of skates did
Marrrta [24]

Answer: Total number of pairs =872

Step-by-step explanation:

Since we have given that

Number of pairs of  skates during the month of April =218

Number of pairs of skates during the month of May =3 × 218=654

As we know that total means altogether in which we perform the additive operation.

Total pairs of skates the skating rent during April and May = 218+654=872

∴ Total number of pairs =872

The Question Is:
lora16 [44]

Answer:

C)  ∠3 and ∠6  is the CORRECT OPTION.

Step-by-step explanation:

Here, the image is UNATTACHED. Attaching image here for the reference.

Given: JL and MP are parallel.

Alternate Interior angles is a pair of angles formed when there is a common intersecting line between two parallel lines.

As JL and MP are parallel.

and KN is a traversal. So, the pair of Alternate Interior angles  so formed are:

a)   ∠3 and ∠6

b)   ∠4 and ∠5

Now, out of the given options:

A.  ∠3 and ∠4  is a LINEAR PAIR

B.  ∠1 and ∠6  makes no pair

C. ∠3 and ∠ 6  is a Alternate Interior angles pair

D.  ∠5 and ∠6 LINEAR PAIR

Hence, ∠3 and ∠ 6  is a Alternate Interior angles pair.
