Can someone explain how to get the answer to this? i keep getting 8.23 when the answer should be 18.24.. the equation is 8.85-71.4÷(-5.1-2.5)

First step you would do is rewrite the equation as

8.85- 71.4-5.1-2.5. From there, you would subtract 2.5 from -5.1, getting -7.6. The equation would now be: 8.85-71.4/-7.6. Next, you would divide 71.4 by -7.6. That would be − 9.394, (rounded two the nearest hundredth would be -9.39.). Then, you would multiply -9.39 by -1, which makes it 9.39. After that, the problem would be 8.85+9.39, which equals 18.24.

If you're more of a visual learner, here's it drawn out! Hope this helps! Please mark brainliest! Thank you v much! :)

1. sometimes

2.   never

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
