Answer:
area of a 1st
Step-by-step explanation:
Ok so first we find the equation that equals one variable.
2y = -x + 9
3x - 6y = -15
We solve for y.
2y = -x + 9
y = -x/2 + 9/2
Then we plug in this y value into the other equation to keep only one variable so we can solve for it.
3x - 6y = -15
3(-x + 9/2) - 6y = -15
-3x + 27/2 - 6y = -15
-9y + 27/2 = -15
-9y = 3/2
-y = 3/18
y = -3/18
Then we plug in this numerical y-value into the first equation which we found out by solving an equation for y.
y = -x/2 + 9/2
-3/18 = -x/2 + 9/2
-84/18 = -x/2
-x = 9 1/3
x = -28/3
Your answer would be (-28/3, -3/18)
Hope this helps!
1) Unknown info = amount of potting soil he bought last week
2). 28=2x+4
Where x=amount of potting soil he bought last week
3). 28=2x+4
-4 -4
---------------------
24=2x
/2 /2
----------------------
X=12
4) Emmanuel bought 12 lbs of potting soil last week
Answer:
I think it depends on the individual and the support system that you have because I came out at 13 and it was the hardest thing I've ever done. But I also have an aunt who was scared and didn't come out till last year and she's 57 years old.
