The simplest I can put it
10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)
5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places
Same works for numbers smaller than zero
5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places
-250 feet most likely is the answer
Not for sure tho but slightly sure lol
Let S = the original price of the sweater. Now, lets step through the problem...
The friend goes shopping with $35 and ends up left with $10.50. This means she spent 35 - 10.50 = 24.50 on the sweater after the sale and coupon.
Next, the sweater is on sale for 50%. This means we take S and take 50% of that. S*.50
Next, she uses a $5 off coupon. Thus, we want to subtract $5 from the price.
Lets combine this all together!
24.50 = S*.50 - 5
Solve for S.
24.50 = S*.50 - 5
29.50 = S*.50
$59 = S
Thus, the original price of the sweater was $59.
6 consecutive even numbers...x, x + 2, x + 4, x + 6, x + 8, x + 10
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 126
6x + 30 = 126
6x = 126 - 30
6x = 96
x = 96/6
x = 16
x + 2 = 16 + 2 = 18
x + 4 = 16 + 4 = 20
x + 6 = 16 + 6 = 22
x + 8 = 16 + 8 = 24
x + 10 = 16 + 10 = 26
ur numbers are : 16,18,20,22,24,26
