Perimiter=sum of all sides
x+x-4+x-4=19
3x-8=19
add 8 both sides
3x=27
divide both sides by 3
x=9 inches
x=9 in
<span>First, you need to find out how much will the candle cost per volume. If a candle with a volume of 80cm^3 costs $12, the price of the candle per cm^3 would be: $12/80cm^3= $0.15/cm^3
Then the price of a candle with </span>120 cm^3 volume would be:120cm^3* $0.15/cm^3= $18
Recall that an equation in slope-intercept form is as follows:
where m is the slope of the line, and (0,b) is the y-intercept.
Substituting m=-6, and b=-1/2 we get:
Simplifying the above result we get:
Answer:
Multiplying by 2, the next one would be 160
Answer:
18 ounce package for $6.30
Step-by-step explanation:
For each one, you divide the money by the package to see how much it is per ounce.
2.59 / 7 = $0.37 per oz
4.56 / 12 = $0.38 per oz
6.30 / 18 = $0.35 per oz
