12! = 12x11x10x9x8x7x6x5x4x3x2x1 =479,001,600
3! = 3x2x1 =6
13! = 6,227,020,800
6,227,020,800 x 6 = 37,362,124,800
479,001,600/37,362,124,800=0.0128
Answer:
30% discount
Step-by-step explanation:
To find the percent discount write a proportion.
Cross multiply numerator with denominator of each fraction to solve for x.
1344(100) = 1920(x)
134400 = 1920x
70 = x
This means you pay 70% of the price. The discount was 30%.
X and y =4? is there more information about the question?
Answer:
AYOOOOO MONEY CHECK
Step-by-step explanation:
6x – 4y = 9
4y = 6x - 9
y = 6/4 x - 9/4
y = 3/2 x - 9/4 this line has slope = 3/2
perpendicular line, slope is opposite and reciprocal so slope of this line = -2/3
answer:
A. y= - 2/3 x - 4 (only this line has slope = -2/3)
