Answer:
4x + 2y
Step-by-step explanation:
If you subtract 5x + 3y from 9x + 5y, you get:
9x + 5y
<u> - 5x + 3y</u>
4x + 2y
Answer:
Let's denote:
The cost of buying 1 burger: x
The cost of buying 1 drink: y
Then, we have:
5x + 3y = 13 (1)
3x + 5y = 11 (2)
Add up both sides of (1) and (2):
=> 8x + 8y = 24
=> x + y =3 (*)
Subtract both sides of (1) to (2):
2x - 2y = 2
=> x - y = 1 (**)
From (*) and (**):
x = 2
y = 1
=> The cost of buying 2 burgers and 2 drinks: 2(x + y) = 2(2 + 1) = 6$
Answer: The length is 13 inches and the width is 11 inches.
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the area of a rectangle is expressed as
Area = LW
The area of the rectangle is 143 square inches. This means that
LW = 143 - - - - - - - - - - - - --1
The rectangle's length is 2 in more than its width. This means that
L = W + 2
Substituting L = W + 2 into equation 1, it becomes
W(W + 2) = 143
W² + 2W - 143 = 0
W² + 13W - 11W - 143 = 0
W(W + 13) - 11(W + 13) = 0
W + 13 = 0 or W - 11 = 0
W = - 13 or W = 11
Since the width cannot be negative, it means that W = 11
L = W + 2 = 11 + 2
L = 13
