Answer:

The correct option is C.

Step-by-step explanation:

The given expression is the sum of two matrices.

[ –6   –2    2] + [–3   2   1]

Both are row matrices of order 1 × 3.

We can add two matrices if and only if order of both matrices is same.

In addition of two matrices, we need to add the corresponding elements of the matrices.

[ –6   –2    2] + [–3   2   1]  =  [ -6-3    -2+2   2+1 ]

[ –6   –2    2] + [–3   2   1]  =  [ -9    0   3 ]

The sum of given matrices is [ -9    0   3 ]. Therefore the correct option is C.

Ari stocks shelves at a grocery store.He puts 35 cans of juice in each display case.The case has 4 shelves with an equal number
ICE Princess25 [194]

Answer:

There are 8 cans on each of the equal shelves

Step-by-step explanation:

Total number of cans put in display = 35

Shelves with equal no of cans =  4 Shelves

And one shelf displays only 3 cans

Therefore, 4 shelves with equal no of cans + 1 shelf with 3 cans = 35 cans

Let us assume equal no. of cans be x

We get, 4x + 3 = 35

             4x = 35 - 3

             4x = 32

              x  = 32 ÷ 4

              x = 8

<u><em>Thus, 4 shelves with equal no of cans contains 8 cans each.</em></u>

Please help!<br><br><br> Solve the inequality for x<br><br> 3(x + 4) &gt; 4 - X
Maurinko [17]

Answer:

x>-2

Step-by-step explanation:

3(x + 4) > 4 - X

Distribute

3x+12> 4-x

Add x to each side

3x+12+x > 4-x+x

4x+12 > 4

Subtract 12 from each side

4x+12-12>4-12

4x> -8

Divide each side by 4

4x/4 > -8/4

x>-2
