Answer:
x = 3 1/2
Step-by-step explanation:
You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.
<h3>Solution</h3>
(5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given
(5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides
(5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7
31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators
21/6 = x = 7/2
x = 3 1/2
<u>So the equation to find the sum of interior angles is 
, with n = number of sides.</u> In this case, this is an octagon (8 sided polygon), so plug in 8 into the equation to solve:
<u>The sum of the interior angles is 1080°</u>
In the table, y is not a function of x .
Changes in x cause no change in y .
Answer:
E
Step-by-step explanation:
They would use 8 signs because one mile in this case is broken up into quarters so in a mile it would have 1/4 1/2 3/4 and 1 mile times that by two because they are placing signs for 2 miles so 4+4= 8
