Answer:
y = 12
Step-by-step explanation:
set up equation for 'y varies inversely with x': y = k/x
where 'k' is the constant of variation
8 = k/6
therefore, k = 48
value of y when x = 4: y = 48/4; therefore, y = 12
Answer:
Infinite solutions
Step-by-step explanation:
You can put in any number for x and the 2 sides of the equation will equal each other.
Answer:
Step-by-step explanation:
This is an Isosceles triangle, two of the angles are equal
A triangle has how many degrees in it? 180°
A two angles that form a line also has 180°
Think of two right angles 90° + 90° = 180° (I wish i could draw on this)

<u>90°|90°_</u>
<u />
angle SRT = angle STR = 20°
angle STR + angle STU = 180°
20° + angle STU = 180° subtract 20° from both sides
angle STU = 160°
angle STU = 4x subs in 160°
160° = 4x divideboth sides by 4
40° = x <---------------- FINAL ANSWER D

I believe you can use ratios and multiply both of them like fractions to get the same amount of bottles and compare the prices fairly.
2:8 = 2/8
1.5:3 = 1.5/3
(2/8)3 = 6/24 or $6 per 24 bottles
(1.5/3)8 = 12/24 or $12 per 24 bottles
In conclusion, the latter ($1.50 for 3) costs more than the $2 per 8.
