The sun of two numbers is 17. One number is 3 less than 2/3 of the other number what is the lesser number? A. 5
B. 3
C. 7
D. 12

lesser # is 5

other # is 12

Step-by-step explanation:

x = lesser #

x + y = 17

x = 2/3y - 3

let 'y' = 17-x

substitute 'y':

x = 2/3(17-x) - 3

x = 34/3 - 2x/3 - 9/3

add 2x/3 to each side to get:

5x/3 = 25/3

multiply each side by 3/5 to get:

x = 25/5 or 5

5 + y = 17

y = 12

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

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
