A writing workshop enrolls novelists and poets in a ratio of 5:3. There are 24 people at the workshop. How many novelists are there and how many poets are there?

Answers

Answer:

\boxed{\sf \ \ \ 15 \ \ novelists \ \ and \ \ 9 \ \ poets \ \ \ }

Step-by-step explanation:

hello,

let's note a the number of novelists and

b the number of poets.

we know that a = 5/3 b as "enrolls novelits and poets in a ratio of 5:3"

it comes 3a=5b which is the first equation

and we know that a + b = 24 "there are 24 people"

we we have two equations

(1) 3a - 5b = 0

(2) a + b = 24

let's multiply (2) by 3 it comes 3a + 3b = 24*3 = 72

let's do 3*(2) - (1) it comes

3a + 3b -3a + 5b = 72 - 0 = 72

so 8b = 72

so b = 9

and then we replace b in (2) it comes

a = 24-9 = 15

hope this helps

a store has apples on sale for 3.00 for 2 pounds. how many pounds of apples can you buy for $9. if an apple is approximately 5 ounces how many apples can you buy for $9. explain your reasoning

Answers

If two pounds of apples cost $3.00 you can buy 6 pounds for $9.
3÷2 = 1.5, so you can buy 1 lb of apples for $1.50
9 ÷ 1.5 = 6, so you can buy 6 lbs of apples for $9
There are 16 ounces in a pound, so  6 pounds is equal to 96 ounces (6*16)
96 ÷ 5 is 19.2
You cant buy 0.2 apples, so 19.2 must be rounded down to 19 apples

You can buy 19 apples for nine dollars.
16oz in a pound.
you can only buy 6lbs.
1lbs of apples would be 3 with one Oz remaining.
6lbs of apples would have 6oz remaining. so that'd be an extra apple.
6lbs of apples would be 18 apples.
18+1=19
19 apples

What is 8.61 to the nearest tenth?

Answers

8.61 to the nearest tenth is 8.6

8.61 would be 8.7 because you would use the 8 to round and if the number is larger then 5 then you raise the score if its lower then you lower the score

"5 or more raise the score 4 or less let it rest"

a good way to remember that
