Assume the following conditional statement is:

If p \to q

It means:

If p, then q

The contrapositive is gotten by negative p and q

i.e.

If \lnot p \to \lnot  q

The above means:

If not p, then not q

Using the above analysis.

The conditional statement from the question is:

If a polygon is a parallelogram, then it is not a trapezoid.

The keywords to negate, which gives the contrapositive, are:

is a parallelogram

is not a trapezoid

When negated, the keywords become:

is not a parallelogram

is a trapezoid

So, the contrapositive is:

If a polygon is not a parallelogram, then it is a trapezoid.

What is the best description of AB?
Wewaii [24]

9514 1404 393

Answer:

  F  altitude

Step-by-step explanation:

AB is perpendicular to triangle base XZ, so is an altitude of the triangle.

__

<em>Additional comment</em>

B is not the midpoint of XZ, so AB is not the median and not a bisector of XZ. Likewise, AB is not the angle bisector of angle A. (The triangle would have to be isosceles for AB to be a perpendicular bisector, median, and angle bisector.)

Eliminating the choices that can't work leaves the one that does work. AB is the altitude.

The cost for 15 cases of oranges is $75. What is the cost for 1 case? *
postnew [5]

Answer:Ok I This question can be solved using a system of equation, which requires translating the above word problem into something that can be algebraically

Let O=oranges and  Let G=Grapefruit

5O +8G=235

3O + 2G=85

To solve, you must isolate one of the variables and then work from there. To do that multiply both sides of the bottom or second equation by four and then subtract the bottom equation from the top.

Which would look like this

5O +8G=235

12O + 8G= 340

Then subtract the bottom from the top to get this

-7O=-105

Solving for O we divide both sides by -7, and end up with O=15

Plugging that value back into one of our original equations to solve for G we get this

3(15) + 2G= 85

45 +2G=85

2G=40

G=20

So 1 case of each altogether would equal 15+20, or $35.
