First of all you need to put a table up so people know what you're talking about, but It just so happens I'm a student as well, so the answer is 5 because the question ask how many people are 12 years or older there are 3 12-14 kids and 2 15-17 kids so 3+2=5
Answer:
10001 is the answer to your Question
Answer:
x=0
Step-by-step explanation:
In the second equation you are given what Y equals, which is (-5x - 3). You would use this equation and plug it into the y value given in the first equation where it says 2y and solve
That would be
3x - 2(-5x - 3) = -6
3x + 10x + 6 = -6
3x + 10x = -6 - 6
13x = -12
X = -12/13
Then if you want to solve for Y you can use any equation and plug in the x-value found.
I’m going to use equation 2.
Y = -5x - 3
Y = -5(-12/13) - 3
Y = 4.615 - 3
Y = 1.615
(-12/13, 1.615)
Therefore the x-value is -12/13 and the y-value is 1.615.
