2t+2d+2c=30
2(8.50)+2(3.50)+2(3.00)=$30
t representing tickets d representing drinks c representing candy
the answer really depends on how much of each item they buy
if they bought more than 2 of each just change the 2 to the number of items bought
Discriminant = square root (b^2 -4*a*c)
square root (64 -4*1*12) =
square root (16) =
4
Therefore it has 2 rational soltions
Hello from MrBillDoesMath!
Answer:
n = 5
Discussion:
-19 - 7n = -6(n+4) => Given
-19 -7n = -6n + (-6)(4) =>
-19- 7n = -6n - 24 => Add 6n to both sides
-19 -7n + 6n = (6n -6n) - 24 =>
-19 -n = 0 -24 => Add n to both sides
-19 (-n +n) = n - 24 => Add 24 to both sides
(-19 +24) + 0 = n =>
+5 = n

Mathematical models are helpful. Advantages include helping you see the data clearer and helping you visualize. Disadvantages are: time consuming, and if you make a mistake on the graph, its going to hit the entre thing.
Answer:
In the given shapes above, we can see that all shapes have four sides.
Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.
First two shapes are Rectangles.
Third is a parallelogram.
Fourth and fifth shapes are Rectangles again.
Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)
Below shown shape has only three sides in it.
It is called a triangle when a shape has three sided close figure.
So, we could drag : Not similar - Different Type of shape.
