Answer:

5

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix 5\times 7 the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.

Answer:

Total overripe fruit = 48

Step-by-step explanation:

<em>Step 1: Assume the value of oranges</em>

Let oranges be x

Oranges = x

Apples = 32 + x

Overripe oranges = 3/5 of oranges

                              = 3x/5

Overripe apples = 1/3 of apples

                           = 1/3 (32 + x)

<em>Step 2: Find x (oranges)</em>

<em>Number of overripe apples and number or overripe oranges are equal.</em>

3x/5 = 1/3 (32 + x)

3 (3x) = 5(32 + x)

9x = 160 + 5x

4x = 160

x = 40

<em>Step 3: Find the total number of overripe fruit.</em>

Total overripe fruit = Overripe apples + Overripe oranges

Total overripe fruit = 1/3 (32 + x) + 3x/5

Total overripe fruit = 1/3 (32 + 40) + 3(40)/5

Total overripe fruit = 24 + 24

Total overripe fruit = 48
