The general equation is that for every red tile, there must be 12 blue ones.
Algebraically this is expressed as b = 12r where r is red and b is blue. Your teacher might like you to express it as y = 12x where y is blue and x is red. The meaning is the same.
For beginners it might be easier to say b = 12r. So if you have 15 reds then r = 15
b = 12 * r
b = 12 * 15
b = 180 blue tiles.

Step-by-step explanation:
25% is furniture, and furniture costs $3600.
So, 3600 x 4 is the total cost, which equals 14400
No 2/3 of $21 is $14 so 6x14 is $84 less than $110
Answer:
When I first saw you... and you act like a baka..
Step-by-step explanation:
X² + 3x = 10
Convert to standard form.
x² + 3x - 10 = 0
factor x² = x * x
factor -10 = 5 * -2
(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0
x + 5 = 0 x² + 3x = 10
x = -5 -5² + 3(-5) = 10
25 - 15 = 10
10 = 10
x - 2 = 0 x² + 3x = 10
x = 2 2² + 3(2) = 10
4 + 6 = 10
10 = 10
