Answer:
C) (-4, 2)
Step-by-step explanation:
It is easier to begin by putting the y equation back into the x equation so it would be rewritten as:
x= 2 (-2x - 6) - 8
Since you replace the y for the given y value
Distribute and you get
x = -4x -12 -8
Add 4x to both sides to get rid of it on the right and balance the equation
5x = -12-8 which is -20
5x = -20
divide by 5 gives you the value -4 for the x
Now simply put that value in for the y equation
y= (-2 (-4)) -6
y = 8 - 6
y = 2
Considering Reid ate 1/4 of the pie and Joe ate 1/3 of the pie, we have to bring this to their common denominator. In this case that is 12.
1/4 + 1/3 = ?
(1 * 3)/12 + (1*4)/12 =
3/12 + 4/12 =
(3 + 4)/12 =
7/12
But this is the amount of the pie that both Reid and Joe ate.
To calculate the remaining amount we have to imagine our pie was still whole (12/12)
and substract what they both ate (7/12):
12/12 - 7/12 = 5/12
Only 5/12 of the pie was left, a little less than half of it :)
X/2 +x/4 =12
(1/2+1/4)x= 12
3/4x =12
by multiple both sides by 4/3
so x = 16
