5x+100=10x
-5x on both sides (10x-5x=5x)
100=5x
divide by 5 on both sides (100/5= 20)
20=x

First, you can rewrite the equation as 5x-10x=-100. You need to do this so that you can carry “x” to one side in order to solve it. Thus, 100 becomes -100 because you’re carrying it to the other side. Then, you subtract. 5x-10x is -5x. Now your equation is -5x=-100. Divide both sides by -5, so that you remove the negative and the coefficient. -100/-5 is 20. This, x is equivalent to 20. You can check your work by substituting the value 20, instead of “x”.

Jason and Maria are playing a board game in which three dice are tossed to determine a player's move. Find each probability for:
fredd [130]
Tossing a die will have 6 possible outcomes. Those are having sides that are number 1 to 6. The sample space of tossing 3 dice is equal to 6³ which is equal to 216. Now for the calculation of probabilities,

P(two 5s) = (1 x 1 x 5)/216
As we have to have the 5 in the die for two times, then for the 1 time, we can have all other numbers except 5. The answer is 5/216. 

P(three 5s) = (1 x 1 x 1)/216   = 1/216

P(one 5 or two 5s)  = (1 x 5 x 5)/216 + (1 x 1 x 5)/216 = 5/36

Solve the equations<br>Y=2x-4, 3x+y=1​
liberstina [14]

Step-by-step explanation:

y = 2x - 4

3x + y = 1

y = 1 - 3x

Equating,

2x - 4 = 1 - 3x

2x + 3x =  1 + 4

5x = 5

x = 1

Placing it,

y = 1 - 3(  1)

y = 1 - 3

y =  - 2
