3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.
Step-by-step explanation:
<u>DATA:</u>
Length of strips Eli need is 2.5 feet long
Length of roll of ribbon is 7.5 feet long
Number of strips that can be cut from the 7.5 feet long roll is x
<u>SOLUTION:</u>
To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.
Number of strips that can be cut = 
x = 
(expression)
x = 3 strips
Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

The surface area without rounding is: 628.32
Answer:
Three equivalent expressions are -3(5-2x), 6x-15, and 3(2x-5).
Step-by-step explanation:
They are equivalent because they equal the same value for x and make the same answer.
<h3>
Therefore they are perpendicular.</h3>
Step-by-step explanation:
A equation of line is
y =mx +c
Here the slope of the line is m.
Given equations are
x - 2y = 18
⇔-2y = -x +18
............(1)
and 2x + y = 6
⇔y = -2x +6 ............(2)
Therefore the slope of equation (1) is
= 
Therefore the slope of equation (2) is
= -2
If two lines are perpendicular, when we multiply their slope we get -1.
therefore,
=. (-2) = -1
Therefore they are perpendicular.
