The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs

<h3>Equation</h3>

  • Total attendance = 75 people
  • Cookies in each pack = 12
  • Brownies in each pack = 15
  • Number of cookies pack = c
  • Number of brownies pack = b

15b + 12c = 75

If 1 package of brownies is bought

15b + 12c = 75

15(1) + 12c = 75

15 + 12c = 75

12c = 75 - 15

12c = 60

c = 60/12

c = 5 packs

  • It is a reasonable value in this context

If 9 packages of brownies are bought

15b + 12c = 75

15(9) + 12c = 75

135 + 12c = 75

12c = 75 - 135

12c = -60

c = -60/12

c = -5 packs

  • The value is not reasonable in this context

A parallelogram has vertices (-3,4) (4,4)(2,-1) (-5,-1) on the coordinate plan what’s the area
Anon25 [30]

Answer:

Area of this parallelogram: 35.

Step-by-step explanation:

What's the equation for the area A of a parallelogram?

A = b · h,

where

  • b is the length of the base, and
  • h is the length of the height <em>on that base</em>.

Plot the four vertices on a cartesian plane. Two opposite sides of this parallelogram are parallel to the x-axis. As a result, the length of the base is the same as the difference in x-coordinates between two vertices on that side. As seen on the diagram, the length of this base is b = 2 - (-5) = 7.

The height on either of those two sides will be normal to the x-axis and parallel to the y-axis. The length of those heights will be the same as the difference in y-coordinates between two vertices, one on each line. As seen on the diagram, the length of the height on base <em>b</em> is h = 4 - (-1) = 5.

Area of this parallelogram:

A = b · h = 5 × 7 = 35.
