The answer is -1 because when cross simplifying you get 0/2-2/0 which =-2/2 and that simplified is -1
The answer is -1
Answer:
Step-by-step explanation:
x=number of talk mnutes
Sage uses 7 minutes = x-7
Tom uses 4 and 3 minutes = x-4-3 = x-7
The perimeter of a rectangle, is all of the sides added up.
In a rectangle, there are two widths (right and left), and two lengths (up and down)
So:
Perimeter = 2 × width + 2 × length.
To get the equation we just substitute in the values that we are given:
length = (x)
width = (x - 4)
perimeter = 87
So just put these values into: perimeter = 2 × width + 2 × length:
87 = 2(x) + 2(x - 4)
_____________________________
Answer:
The equation is: 87 = 2(x) + 2(x - 4)
<em>(note: this can be simplified down like so:</em>
<em>87 = 2x + 2x - 8</em>
<em>87 = 4x - 8</em>
<em>95 = 4x</em>
23.75 = x
