Answer: <u>C. 20-.40p</u>
Step-by-step explanation:
We know that from the given information that each pound is worth 40 cents, and that its being subtracted from the twenty dollar bill.
"Why are the others choices wrong?"
A. p-20, isn't the proper equation due to the stated information.
B. B. 20 -40p, this equation has Zelma pay $40 dollars each pound, which isn't correct due to what the text has stated ("for 40 cents per pound").
D. 40p-20, from the given text, this equation is wrong ("She pays the clerk with a twenty-dollar bill), it never states that she will be charged twenty dollars, or be given forty for each pound.

Answer:
the radius if the measurement of the circle for the center
Answer:
1/3
Step-by-step explanation:
6+4+5=15 total number of balls
blue = 5 balls
5/total number = 5/15
=1/3
The slope of a line perpendicular to another line has a
slope which is the negative reciprocal of that line or:
m1 = -1/m2
First, we convert the given equation into slope-intercept
form of a line: y = mx + b
8x + 15y = 12
15y = -8x + 12
y = (-8/15) x + 0.8
m1 = -8 / 15
Therefore the slope of the perpendicular line is:
m2 = 15 / 8
Since the perpendicular line crosses the point (11, 17), therefore
using the slope formula:
m = (y2 – y1) / (x2 – x1)
15 / 8 = (y2 – 17) / (x2 – 11)
1.875 (x2 – 11) = y2 – 17
1.875 x2 – 20.625 = y2 – 17
y2 = 1.875 x2 – 3.625
y = (15/8) x – 3.625
multiplying both sides by 8:
8y = 15x – 29
rewriting in standard form:
