How do you know if a quadrilateral is a parallelogram?

Answers

If a quadrilateral is a parallelogram then opposite sides are parallel. For example, look at the diagram I provided below. If quadrilateral A,B,C,D is a parallelogram, then side A,B is parallel to side D,C. Also, side A,D must be parallel to side B,C.

Hey there! :D  So you're wondering how you can tell if a quadrilateral is a parallelogram, right? Well, you are about to find out! The way you can tell whether a quadrilateral is a parallelogram because we know that a quadrilateral has 4 sides, right? And a parallelogram is a figure with opposite sides that never intersect or cross. So for example, a square is a quadrilateral and it has 4 equal sides and if we extend the lines horizontally, the would not cross.

I hope this makes sense to you! Have a good evening!(If you are in the US, but if you aren't, good morning!) :D

justin and tyson are beginning an exercise program to train for football season. Justin weighs 150 pounds and hopes to gain 2 pounds per week. Tyson weighs 195 pounds and hopes to lose 1 pound per week. if the plan works in how many weeks will the boys weigh the same amount. what will the weight be

Answers

It will take Justin and Tyson 15 weeks to both be 180 pounds. You just do 150+2*15=180 and then you would do the other one 195-1*15=180 and they both equal the same.
it will take 15 weeks for them to be the same weight.

What is (7/12)/(5/9)? In simplest form..

Answers

(7)/(12) / (5)/(9) =

Change the division to multiplication through the reciprocal of the number being divided. 

(7)/(5) * (9)/(5) =  (21)/(20)

As mixed number:

1 (1)/(20)
7/12 times 5/9 equals 35/108. It is automatically in simplest form.

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.

Answers

Answer:

Hm, okay.

Step-by-step explanation:

So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.

$16.85 - $12.50 = $4.35

So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?

We divide $4.35 by 3.

$4.35 / 3 = $1.45.

So, the amount of money spent on one large drink was $1.45.

If t+8=-12 what's the value of t + 1

Answers

To find out what t + 1 is, we first must find out the value of t.
We know that t + 8 = -12, so all we need to do to solve for t is subtract 8 from both sides.

t + 8 = -12

t + 8 - 8 = -12 - 8

t = -20

So now that we know the value of t, all we need to do to find t + 1 is insert the value of t into the variable and solve.

t + 1 = ?

-20 + 1 = ?

-19

And there we have it.
t + 1 = -19
Hope that helped! =)
the reason it gives us t + 8 = -12 is because they want us to figure out what t is. this is very simple trust me:) given our problem.
t + 8 = -12 what we have have to do here is isolate t alone. lets subtract 8 from both sides.
t + 8 = -12 
   - 8 = - 8     the 8 on the left hand side of the equal side is canceled out! and  we have to subtract 8 from -12. lets do the math:)
-12 - 8 = -20 well lets see what we have left of our problem.
t = -20
hey we have our answer we know that t = -20
but the question is asking us to find the value of t + 1 
well lets plug -20 for t
-20 + 1 = -19 since we are adding 1 it moves plus 1 towards the number zero.
so whats the answer? you may be asking..
-19
have a good one :)

merry christmas:D
