Given:
Gil buys 4 books for $16. Then he sells 3 CDs for $27.
To find:
The equations for y, Gil’s change in money after buying a book, and for x, his change in money after selling a CD, in standard form.
Slope of each equation.
Solution:
Gil buys 4 books for $16.
4 books = $16
1 book = $4
Let n be the number of book purchased, then change in money after buying n book is

Here, negative sign represents decrease in money. Here, slope of -4 it means the money decreased by $4 after buying each book.
He sells 3 CDs for $27.
3 CDs =$27
1 CDs =$9
Let c be the number of CDs sold, then change in money after selling m CDs is

Here, slope of 9 it means the money increased by $9 after selling each CD.
X = 89
A triangle always equals 180°. Because two out of three angles are given, the two known angles (42° and 49°) can be added together which is 91°. The 91° can be subtracted from 180° to find the unknown angle x.
Answer:
45 yards and 176 yards
Step-by-step explanation:
Perimeter of a rectangular playing field = 2(Length + width)
P = 2(L+W)..................... Equation 1
From the question,
Let the width of the rectangular playing field = x yards,
The the Length = 4x-4 yards.
Given: P = 442 yards.
Substitute these values into equation 1
442 = 2(4x-4+x)
442/2 = 5x-4
221 = 5x-4
5x = 221+4
5x = 225
x = 225/5
x = 45 yards.
Width = 45 yards.
Length = (45×4)-4 yards = 176 yards
Hence the dimensions of the playing field are, 45 yards and 176 yards
Pounds.. or grams it depends on what size the pitcher is.. but pounds
Answer:
True
Step-by-step explanation:
We actually can use Sine, Cos, or Tangent to solve for the angles, which would give the angle, but graphing it came up with an Obtuse Scalene triangle.
