Answer:

x=8

y=13

Step-by-step explanation:

This shape is a parallelogram, and in a parallelogram, the diagonals bisect eachother. So then, you can write to equations:

2x=y+3

x+5=y

This is equal to:

2x-y=3

x-y=-5

Then, you can subtract the two equations, making it:

2x-y=3

-x+y=5

Then the result will be:

x=8

Now that we know what x is, you can find y by plugging it in to either equation.

8-y=-5

-y=-13

y=13

Hope this was helpful!

Find x for <br> 5x+5+65+65=
Phoenix [80]

5x+5+65+65=

Answer:

x=-27

Step-by-step explanation:

We want to find x right, so everything that does not have x you can move to the other side. 5x=-5-65-65. So that should be your equation so far. Now we know that when there are two negatives it is a negative and you add so -5-65=-70-65=-135. So your equation now should be: 5x=-135. Now we can divide -135 with 5 which gives us... -27! There’s your answer. Hope this was correct!

Rolands suitcase has a mass of 2,500 dekagrams. How many kilograms is his suitcase?
Tasya [4]
A decagram is 10 grams, so first lets convert the decagrams to grams and then after we'll change to kilograms.
If 1 decagram equals 10 grams, then 2500 decagrams is equal to:
2500*10 = 25000 grams
Now, 1 kilogram equals 1000 grams so 25000 grams equals:
25000/1000 = 25 kg
therefore, 2500 decagrams equals 25 kg
