Answer:
12 Small, 16 Large
Step-by-step explanation:
When you do the math of getting 16 large candles and 12 small candles with respects to the price. You get the math of:
(6×16) + (4×12)
96 + 48
144
16 and 12 will make 28 which proves to be correct as 28 candles were sold
There is a simple algebraic solution to this; a system of equations!

The coordinates of points A, B, and C are (5, 4), (–2, 1), and (4, –4), respectively. Which point, B or C, is closer to point A? Elena-2011 [213]
Answer:
The distance between two points (x1,y1) and (x2,y2) = √((x1-x2)2+(y1-y2)2) Distance between A and B = √((5--2)2+(4-1)2) = √(72+32) = √(49+9) = √58 = 7.62 Distance between A and C = √(12+82) = √65 = 8.06 Point B is closer to A. Another method to solve this problem is to draw the points on a graph paper and measure distance with a ruler.
Answer:
(-20 - 10) / (-12 - (-10))
-30 / -2
30/2
now the midpoint would be half the two points
30/2 ÷ 2/2 = 15/1
So add 15 to -20 (or subtract 15 from 10) for the y, and add 1 to -12 (or subtract 1 from -10) for the x.
Answer:
3x^2 - x - 10
Step-by-step explanation:
Times the two together and you get
3x^2 + (-6x) + 5x + (-10)
Sum these up for your answer
