Algebra 2 find the solution of the equation using a method of your choice

1 answer:

5 0

Take the 28 and tern it into -28 and do it on both sides, -28 + 28 = 0, -28 + -1 = -30.

Sence x represents one aka any number you will add x with 11 and you will get 12x^2

Now you have to divide 12 on both sides, 12 divided by 12 is 1 so it eliminates it, 12 divided by -30 = -2.5, so then X = -2.5, and that should be right

I hope this helps! =)

insens350 [35]

So you have 20% of blue and 50% of black.
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black
