Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
Step-by-step explanation:
Constitution states that the government of the United States holds only those powers specifically granted to it by the Constitution;loose:interpretation of the Constitution posits that the government of the United States hold all powers that are not specifically denied to it by the Constitution
There were 20 football players in the room. Because the ratio of football players to soccer players was 5 to 7, that meant that, should the ratio represent the actual number of football players in the room, there would be 12 football players in the room. However, the ratio has to be set equal to accomodate the 48 football players, therfore the 12 hypothetical players in the room would have to be multiplied by 4 to equalize. But that also means that everything else in the ratio will have to be multiplied by 4 to truly balance the ratio. Since there were 5 out of 12 football players, and there are actually 48 football players, and 12 times 4 equals 48, then 5 times 4 should give us our actual number of football players. Finally, some basic math will tell you that because 5 times 4 equals 20, and we can say that there are actually 20 football players in the room.
−3/7×14/15×7/12×(−30/35)
=(−3/7×14/15)×(7/12×−30/35)
On further calculation, we get
=−2/5×−1/2
We get,
=1/5.
Property 1:
If a/b is a rational number and m is a non-zero integer then a/b =(a*m)/(b*m). In other words, we can say that the rational number remains unaltered if we multiply both the numerator and denominator with the same integer. Ex: 2/3 = 2*2/3*2 = 4/6, 2*3/3*3 = 6/9, 2*4/3*4 = 8/12.
