11. 4x – 6 - 3x = 2 + 5x ! it has to equal 2 -4 -6 -3 or 7! i've tried many times trying to find the value of x!

x = -2

Step-by-step explanation:

4x -6 - 3x = 2 + 5x

4x - 3x -6 = 2 + 5x

1x - 6 = 2 + 5x

-1x = -1x

-6 = 2 + 4x

-2 =-2 + 4x

-8 = 4x

-- = --

4 4

-2 = ×

x = -2

Step-by-step explanation:

4x - 6 - 3x = 2 + 5x

subtract 5x on both sides

4x - 6 - 3x - 5x = 2

combine like terms on the left side

-3x - 5x + 4x = -4x

-4x - 6 = 2

add 6 on both sides

-4x = 8

divide each side by -4

x = - 2

-4

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
