Solve the question: 4/5 (b-1)-1/b=1

Mathematics
1 answer:
soldi70 [24.7K]3 years ago
4 0

Answer:

We know that (4/5b - 4/5 - 1) / b = 1

Which means that b = 4/5b - 4/5 - 1

So we put variable on one side and numbers on the other side

So 1/5b = - 9/5

So b = - 9

Can someone PLEASE help? i need this done!
iren [92.7K]
It would be .43, rounded. You get this answer by taking all of the 10th graders (14) and looking at how many prefer sporting events (6). Then, you simply form a decimal from 6/14, and that comes out to .428, and .43 rounded up. I hope this helps! :)

What is the result of the first step when simplifying 13-4(x-5)
Maksim231197 [3]
I don't really get this question but simply put, if you are in college syntax matters very much. (13-4) = 9 *(x-5) = 9x-45.. although in this case. since there isn't a bracket around 13-4. you'd multiply by the -4 first, giving you, 4x-20+30 =4x-10

❗️HELP ASAP❗️
tangare [24]
I think the answer is G.

I think this because of the fact families (like my elementary teacher used to say)
It’s like about multiplication of fact families so make it where it would have fact families with those numbers as the sums.
I hope this helps! Be safe out there.
