Answer:
There are 36 Possibilities.
Step-by-step explanation:
If you role the dice it will have 6 options so 6 Possibilities. 6 times the number of times the dice has been rolled would be 30 and since their are 6 Possibilities they would be added so that would equal 36.
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
Answer:
mEOP is 29°
Step-by-step explanation:
mHOP is 48° and mHOE is 19°, so to get the missing angle you subtract the smaller value from the total to get 29°
- 19-48=29
Answer:
Option A.
Step-by-step explanation:
The given equation is
Liliana wants to write an equivalent expression.
It can be written as
Using commutative property, we get
![[\because A+B=B+A]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2BB%3DB%2BA%5D)
Using associative property, we get
![[\because A+(B+C)=(A+B)+C]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2B%28B%2BC%29%3D%28A%2BB%29%2BC%5D)
Using distributive property, we get
![[\because An+Bn=(A+B)n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20An%2BBn%3D%28A%2BB%29n%5D)
Using addition property, we get
Therefore, the correct option is A.
