36 minutes.
(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
Take the original price and times it by .8 (you could times it by .2 and then subtract from the original price but multiplying it by .8 is much easier) 64.9x.8= 51.92 take your discounted price and multiply it by 1.085 to account for the sales tax (you multiply by 1.085 to account for the price of the item and the tax you could times it by .085 and then add it on to the price of the item but this way it shortens the amount of steps needed) 51.92x1.085= 56.3332
Round to the nearest cent
Answer=$56.33

Step-by-step explanation:
Answer: Infinite solutions.
Step-by-step explanation:
Plug the value of y into the second equation.
Add 12 on both sides.
Add 4x on both sides.
Answer:
x = y + 8
Step-by-step explanation:
Given
y = x - 8 ( add 8 to both sides )
y + 8 = x
