Answer:
First equation x=2, Y=9, Second Eq, x=2, y=1
Step-by-step explanation:
X+Y=11
2X-Y=-5 by substitution Y=11-X
So, 2x-(11-x)=-5, 2x-11+x=-5, 3x=6, x=2. Thus, Y=11-2=9
2x+y=5
3x-2y=4
so, y=5-2x
Thus, 3x-2(5-2x)=4
3x-10+4x=4, 7x=14, x=2, Thus, Y=5-2(2)= 1
A baseball player made six hits in nine innings.
Therefore, his ratio of hits to innings, which means his number of hits relative to the number of innings, is 6:9.
However, this isn't simplified. To simplify a ratio, we must find the GCF (Greatest Common Factor) of the two terms.
The GCF of 6 and 9 is 3, thus, we divide both of the terms by 3 to get our simplified answer.
6:9 = 6/3 : 9/3 = 2:3
Your answer is that the ratio of hits to innings for the baseball player is 2:3. (This can also be expressed as 2/3 or 2 to 3.)
Hope this helps! :)
1.5 x 2 = 3 So you do 2.4 x 2 = 4.8 and the answer is 4.8 miles

Answer:
The American population was 20% of the British population.
Step-by-step explanation:
Let us call 
the american population, 
the British population before the migration, and 
the population that migrated from America to Britannia.
Now, the population that migrated was 20% of the american population:
,
and the same population increase the British population by 4%:
Combining equation (1) and (2) we get:
Thus, the American population was 20% of the British population.
