Answer:
100 dollars
Step-by-step explanation:
Let us first establish the fact that losing a bet means that one brother will lose part of his money to another brother, meaning that the sum of their money will remail the same.
Now, it is given that, before the last bet, Marco had $180 and that the ratio Julian: Marco was 2 : 3.
If we make a proportion, we will get;
x : $180 = 2 : 3
x = $120
So, before the last bet, Julian had $120, meaning that the sum of their money was $300.
After the last bet, sum remained the same, only the ratio changed (4:2).
That means that:
4x + 2x = $300
6x = $300
x = $50
So, Julian now has 4 • $50 = $200 and Marco has 2 • $50 = $100.
Answer:
q=1, q=2
Step-by-step explanation: Both values are less than 5 and the others are either equal or higher, which is not included in the inequality. I hope this helps. :)
Answer:
k = 63
Step-by-step explanation:
k/3 - 9 = 12
isolate variable + 9 both sides
k/3 = 21
multiply both sides by three, therefore
k = 63
check:
63/3 - 9 = 12
21 - 9 =12
12 = 12
hope this helps!
