Step-by-step explanation:
When you have something like that, just think that the first number goes on top and the second number goes on bottom.
It would be 16 more 6th graders that are not in either band or orchestra.
15 6th Graders in band
9 6th Graders in both classes
+18 6th Graders in orchestra
-----
42 6th Graders in either class
100 6th Graders in total
-42 6th Graders in either class
-------
58 6th Graders in neither class
58-42= 16 more 6th Graders that are not in either class
You're welcome :)
Explanation:
There are many versions of the taxonomy diagram for quadrilaterals. The details depend on the particulars of the definitions you use. Here, we'll say a parallelogram is a subset of trapezoids. Not all authors would agree.
(2) kite -- two pairs of adjacent same-length sides
(3) trapezoid -- (at least one) pair of parallel opposite sides
(4) parallelogram -- opposite sides are parallel
(5) rhombus -- all sides the same length (and opposite sides parallel)
(6) rectangle -- parallel opposite sides and right angles
(7) square -- same-length parallel opposite sides and right angles

Answer:
x=-1
Step-by-step explanation:
-12=-12(x+12)
multiply -12 and x which equals -12x
multiply -12 and 2 which equals -24
the resulting equation is -12=-12x-24
add 24 on both sides of the equation----> equals -12x=12
divide -12 on both sides of equation
x=-1
