Equations and inequalities are figured the same way except for that one rule with inequalities...multiplying/dividing by a negative number changes the inequality sign.
Basically, u get the variable terms on one side and everything else on the other side...then solve for the variable. The only thing that would make it faster is if u had fractions...u would turn those fractions into whole numbers by multiplying by the lowest common denominator.
Other then that, I dont know how u could make it faster.
Answer: 
Step-by-step explanation:
Given
The Sum of the seven interior angles of an octagon is 
for a Polygon, the sum of the interior angles is given by 
for octagon, n=8
The Sum of interior angles is 
Suppose the eighth angle be 
The 
angle is
If that's how it's displayed, 7/12, then no it doesn't make sense. Using that scale factor is the equivalent shrinking it by 5/12s. And that's not larger than life size. If the scale factor is 7:12, then it would make sense, as the beetle would be 5/19 bigger than the original. It's not much, but it's a start for Penny
x + y = total pieces (23)
bracelets are $2 so 2x
necklaces are $3 so 3y
2x + 3y = 55
Answer:
8 + 4x = 28
Step-by-step explanation:
So in this equation 'x' = 5. Eight more would be 8 +. So you would subtract 8 from 28 giving you 20. From there you would divide by four giving you five thus which is your 'x' variable.
