<h2>Answer:</h2>

The equation which can be used to determine c, the total price of n pounds of blackberries is:

                             c = 1.56n

<h2>Step-by-step explanation:</h2>

The cost of 1 pound of blackberries is: $ 1.56

( since, it was given that: The price of blackberries at a farm is $1.56 per pound )

Also we know that the cost of n pound of blackberries is the product of number of pounds of blackberries to cost of one pound of blackberries.

Hence, the cost of n pounds of blackberries is:

                      c=1.56n

The width of a rectangle is the length minus 2 units. the area of the rectangle is 35 units
Mariana [72]

Answer:

Length=7units\\\\Width=5units

Step-by-step explanation:

Width=(Length-2) units

W=(L-2) units

Area of the rectangle= 35 square units

Area = length* Width

35= L*(L-2)\\\\35=L^2-2L

Subtracting 35 both sides:

L^2-2L-35=0

Solving the quadratic equation for 'L' ;

Using factorization:

L^2+5L-7L-35=0

Taking common from the equation :

L(L+5)-7(L+5)=0\\\\(L+5)(L-7)=0\\\\L+5=0\\\\L=-5

OR

L-7=0\\\\L=7

The length cannot be negative, therefore Length(L)= 7

Width=Length-2\\\\=7-2\\\\=5 units

Length=7units\\\\Width=5units

Answer:

  • apples: $0.50 ea
  • oranges: $0.75 ea
  • avocados: $2.00 ea

Step-by-step explanation:

Let a, o, v represent the prices of one each of apples, oranges, and avocados, respectively. Then the equations describing the purchases can be written ...

  6a +6o +6v = 19.50

  12a +2o +1v = 9.50

  2a +4o +5v = 14.00

__

Dividing the first equation by 6 makes it ...

  a +o +v = 3.25

Subtracting this from the second equation gives ...

  (12a +2o +v) -(a +o +v) = (9.50) -(3.25)

  11a +o = 6.25

Subtracting the third equation from 5 times the reduced first equation gives ...

  5(a +o +v) -(2a +4o +5v) = 5(3.25) -(14.00)

  3a +o = 2.25

The difference of these last two equations is ...

  (11a +o) -(3a +o) = (6.25) -(2.25)

  8a = 4.00

  a = 0.50

Then the other values are ...

  o = 2.25 -3(a) = 0.75

  v = 3.25 -a -o = 2.00

The unit prices are:

  apples -- $0.50

  oranges -- $0.75

  avocados -- $2.00

_____

<em>Additional comment</em>

Most graphing or scientific calculators will solve systems of equations like these. Using an appropriate tool, it takes less time to find the solution than to read this one.

Note that the last purchase description in the problem statement has the items in a different order than in the first two descriptions. Care must be taken to make sure the correct equations are written.
