$7.18 / 2 = $3.59 per pound
.........................................
so 1 lb = $3.59
2 lbs = 2* $3.59 = $7.18
3 lbs = 3 * $3.59 = $10.77....
The ratios that are equivalent to each other are 16:28 and 4:7
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Select all the ratios that are equivalent to each other.

16:28 = (4 * 4): (7 * 4) = 4:7
The ratios that are equivalent to each other are 16:28 and 4:7

Answer:
Step-by-step explanation:
50.
line AB that has the points (2,5) and (9,2) hhas the slope
m= (y2-y1) / (x2-x1)= 5-2 / 2-9 = 3/-7 = -3/7
Parallel line have the same slope so m= -3/7 for the line that has the point (-3,4).
Point-slope equation is y-y1 = m (x-x1), y -4 = -3/4 (x+3) or
you can writte it as y= (-3/4)x - 9/4 +16/4 so y = (-3/4)x + 7/4
51.
line PQ has slope m= -6+1 / 4-6 = -5/-2 = 5/2
Perpendicular lines have their slope negative reciprocal of eachother so the line that goes trough the point (1,3) has the slope m= -2/5
y-3 = -2/5 (x-1)
