Answer:
3 ounces at most
Step-by-step explanation:
0.37 + 0.23 x 3 or 0.37 + 0.23 + 0.23 + 0.23
328 ÷ 4 = 82 mph. (unit rate)
82 x 10 = 820.
Haley can drive 820 miles in 10 hours, and drove 82 miles per hour.

7b+12=5b
Subtraction property of equality
7b + 12 - 12 = 5b - 12
Simplifying
7b = 5b - 12
Subtraction property of equality
7b - 5b = 5b - 12 - 5b
Simplifying
2b = -12
Division property of equality
2b/2 = -12/2
Simplifying
b = -6
Answer:
The actual discount is a 68% discount.
Step-by-step explanation:
Remember that if something has a price P, and you have a discount of the X%, the new price will be:
P' = P - P*(X%/100%) = P*(1 - X%/100%)
Here we first have a 60% discount, then if the initial price is P, the new price is:
P' = P*(1 - 60%/100%) = P*(1 - 0.6)
Now we have an additional 20% discount (this applies to the new price)
then the final price is:
P'' = P'*(1 - 20%/100%) = P'*(1 - 0.2) = P*(1 - 0.6)*(1 - 0.2)
We want to rewrite this as something like:
P'' = P*(1 - k)
Let's do this:
P'' = P*(1 - 0.6)*(1 - 0.2) = P*(1 - 0.2 - 0.6 + 0.2*0.6)
= P*(1 - 0.8 + 0.12) = P*(1 - 0.68)
And this can be as:
P'' = P*(1 - 68%/100%)
Then the actual discount is a 68% discount.
