2x = 10

x = 5

hope u understand

Step-by-step explanation:

let me explain you now

1. collect like terms

2. move the variable to the left hand side and change its sign

3. move the constant to the right hand side and change its sign

4. collect like terms and add the numbers

5. divide the answer with 2

6. the solution

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
