Ahmed is taking orders for lunch. A slice

Mathematics
1 answer:
Wittaler [7]3 years ago
3 0

Answer:

  • x+y=7; 2.5x+3.5y=21.5
  • (x, y) = (3, 4)

Step-by-step explanation:

Perhaps you want a system of equations and their solution.

You have defined the variables, so you just need to write the relationships.

  x + y = 7 . . . . we assume one order per person

  2.50x + 3.50y = 21.50 . . . . we assume Ahmed collected just enough

__

Multiplying the first equation by 2.5 and subtracting that from the second equation, we get ...

  (2.50x +3.50y) -2.5(x +y) = (21.50) -2.5(7)

  y = 4

  x = 7 -4 = 3

There were 3 pizza orders and 4 sandwich orders.

The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100.
Mice21 [21]

Answer:

1. x^2-10 because the area expression can be rewritten as (x^2-10)(x^2+10)which equals (x^2-10)((x^2-10)+20).

Step-by-step explanation:

Area of the rectangle =(x^4-100)

x^4-100=(x^2)^2-10^2\\$Applying difference of two squares: a^2-b^2=(a-b)(a+b)\\(x^2)^2-10^2=(x^2-10)(x^2+10)

Since the length of a rectangle is 20 units more than its width.

Width: x^2-10\\Length=x^2+10=x^2-10+20

The correct option is therefore 1.

1+2=3, 12 divided by 3=4 4x1=4, so there is 4 red marbles. 4x2=8 so there is 8 blue marbles. We can check this is true by adding 8+4 which =12.

blue=8
red=4

Which of the following best describes the parallelograms shown below?​
Nesterboy [21]

Answer:

The statement "Parallelogram 1 and parallelogram 2 are similar because parallelogram 2 can be created by rotating, reflecting, translating and dilating parallelogram 1" is correct.

Step-by-step explanation:

This statement is correct because the two shapes cannot be congruent; parallelogram 2 is a different size than parallelogram 1. They must be similar, and the third statement is the only statement with a dilation.

A programmer wants to display how the shape of a rectangle with a fixed perimeter of 300 inches can be changed by varying the re
stiv31 [10]

If the rectangle has a fixed width of 300, it means that

2(l+w)=300 \iff l+w=150 \iff w=150-l

where w and l are width and length, respetively.

So given the length l, the are would be

l\times w = l\times (150-l)=-l^2+150l
