Answer:
52:49
Step-by-step explanation:
pink:green
The ratio of pink to green marbles is
3k:4k
He removes 5 green marbles and adds 8 pink marbles.
Now the ratio of pink to green marbles is
(3k + 8):(4k - 5)
This rario is equal to 29:23.
(3k + 8)/(4k - 5) = 29/23
29(4k - 5) = 23(3k + 8)
116k - 145 = 69k + 184
47k = 329
k = 7
Original amounts:
3 * k = 3 * 7 = 21 pink
4 * k = 4 * 7 = 28 green
Original total = 21 + 28 = 49
Amounts after replacement:
3k + 8 = 3(7) + 8 = 29 pink
4k - 5 = 4(7) - 5 = 23 green
Total after replacement = 23 + 29 = 52
Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.
Look it up :)))))))))))))
Answer:
37.68 i think
Step-by-step explanation:
Answer:
<h3>A) </h3>
First were going to put our numbers in perspective.
÷ 
But to find the improper fraction, we have to <em>cross multiply</em> these numbers.
×
<em>7 x 5 = 35. </em>
<em>4 x 8 = 32.</em>
Now we have our<em> improper fraction </em>is 
<h3>B) </h3>
To turn our improper fraction into a <em>mixed number</em>, we will use <em>division</em>.
We know that the 32 can only go into 35 <u><em>one</em></u> time. We also know that the bottom number <em><u>always</u></em> stays the same. So our equation will look somewhat like this.

Now to fine the top number we will have to<em> subtract 35 from 32</em> because we already know that 32 can go into 35 <u><em>one</em></u> time, so <em>35 - 32 = 3</em>. So are mixed number will look like this.

This is our <em>answer!</em>
