Alice and Bob each have a certain amount of money. If Alice receives $n$ dollars from Bob, then she will have $4$ times as much
oksano4ka [1.4K]

Answer: 31 : 9

Step-by-step explanation:

Assume the following:

Alice's amount = P

Bob's amount = Q

Amount received = n

If Alice receives $n$ dollars from Bob ;then she will have $4$ times as much money as Bob.

P + n = 4(Q - n)

P + n = 4Q - 4n

P = 4Q - 4n - n

P = 4Q - 5n - - - - (1)

If, on the other hand, she gives $n$ dollars to Bob, then she will have $3$ times as much money as Bob

P - n = 3(Q + n)

P - n = 3Q + 3n

P = 3Q + 3n + n

P = 3Q + 4n - - - - - - (2)

Equating both equations - (1) and (2)

4Q - 5n = 3Q + 4n

4Q - 3Q = 4n + 5n

Q = 9n

Express P in terms of n, use either equation (1) or (2)

From equation 2:

P = 3Q + 4n

Substituting Q = 9n

P = 3(9n) + 4n

P = 27n + 4n

P = 31n

Alice's amount = P, Bob's = Q

Ratio = P:Q

31 : 9

W=2j, m=5w, (m+4)=6(j+4)  

using w from first in second you get:

m=5(2j)=10j, m+4=6j+24

m=10j, m=6j+20, since m=m we can say

10j=6j+20

4j=20

j=5, and since m=10j

m=50

So the man is 50 years old

Find the value of x.
nevsk [136]

Answer:

<h2>x = 30°</h2>

Step-by-step explanation:

Since the figure above is a triangle, all it's angles sum up to 180°

To find x , add up all the angles and subtract them from 180°

That's

57 + 93 + x = 180

150 + x = 180

x = 180 - 50

We have the final answer as

<h3>x = 30°</h3>

Hope this helps you
