Answer:
6
Step-by-step explanation:
I might not be right but I think it's 6 because
24÷4=6
Answer: 12² = 144
12² ÷ 12² = 1
Step-by-step explanation:
I'll go through it backwards: 12^7 times 12^-5 You subtract the -5 from 7 in the exponents to get 12^2. 12^2 divided by 12^2 is 1.
(12^2)^3 works out to 12^6 because you multiply the exponents when its a power raised by a power. Then you subtract the 4 from the 6 (or add -4 +6) to get 12^2.
That means 12 squared, same as 12 times 12
That's 144.
If you have to multiply the two parts together, It's 144 times 1.
If "and" means "add them together"-- YOU KNOW!
Answer:
x = $200
The original price is $200
Question :
The price of a dress is reduced by 50%. When the dress still does not sell, it is reduced by 50% of the reduced price. If the price of the dress after both reductions is $50, what was the original price?
Step-by-step explanation:
Let x represent the original price of the dress.
First reduction
After first reduction the value of the price is given as;
p1 = x - 50% of x = (1-0.50)x = 0.5x
p1 = 0.5x
Second reduction
After the second reduction the value of the price is given as;
p2 = p1 - 50% of p1 = (1-0.50)p1 = (0.50)0.50x
p2 = 0.25x .....1
Since, p2 is given
p2 = $50
Substituting into equation 1
$50 = 0.25x
x = $50/0.25 = $200
x = $200
The original price is $200
