Answer:

6 pounds of green candy

Step-by-step explanation:

Let r be the weight of red candy

Let g be the weight of green candy

Total weight = 10 pounds

r + g = 10 -------------------------(I)

Total cost = $ 38.50

2.50r + 4.75g = 38.50  --------------(II)

Multiply equation (I) by -2.50

(I)* (-2.50)             -2.50r - 2.50g = -25.0

(II)                          <u>2.50r + 4.75g = 38.50 </u>   {Now add and r will be eliminated}

                                        2.25g = 13.50

g =13.50/2.25

g = 6

Plug in the value of g in equation (I)

r + 6 = 10

r = 10 - 6

r = 4

The area of the David's pantry = 10 square feet.

The length of the pantry = 5 feet.

<h3>Define the term area of the rectangle?</h3>
  • The territory inhabited by a rectangle inside its 4 sides or limits is known as its area.
  • The area of such a rectangle is determined by its sides. Essentially, the formula calculating area is equivalent to the product of the rectangle's length and breadth.

For the given question.

  • David's kitchen is 60 square feet in size.
  • The kitchen is six times the size of the living room.

Thus,

Area of kitchen  = 6 x area of the pantry

60 = 6 x area of the pantry

area of the pantry = 60 / 6 = 10 square feet.

Area of the pantry = length x breadth

10 = length x 2

length = 10/2 = 5 feet.

Thus, the length of the pantry is found as the 5 feet.

in circle o, points a and b lie on the circle such that OA=5x-11 and OB=4(x-1) what represents the length of the circle' s diame
AysviL [449]
We know that
if <span>points a and b lie on the circle  and O is the center
so
OA is the radius
OA=OB
5x-11=4(x-1)-----> 5x-11=4x-4----> 5x-4x=11-4-----> x=7
OA=5x-11-------> OA=5*7-11-----> OA=24  units

the diameter is (OA+OB)
2*OA------> 2*24------> 48 units</span>
