Answer:
$99/$115 x 100% = 86.086% of the original price
So 100% - 86.086
= 13.9 = 14%
Or you could just do (115 - 99) x 100 which gets the same answer.
Answer:
x = 5
Step-by-step explanation:
1. Expand
8x - 5x + 5 = 20
2. Simplify
3x + 5 = 20
3. Subtract 5 from both sides
3x = 20 - 5
4. Simplify
3x = 15
5. Divide both sides by 3
x = 15/3
6. Simplify
x = 5
The hypothesis is sometimes the if part in my opinion
A mountaineer climbed 1000 feet at a rate of x feet/hour
1000 = x ( t 1 ) eq1
5000 = X ( t 2) eq2 ( he climbed additional at different rate )
the rate was 10 feet / hour less than twice the first rate
X = 2x - 10 eq3
take eq1 and eq 2
( total time = t 1 + t 2 = T)
T = 1000/x + 5000/X
but X = 2x-10
T = 1000/x + 5000/( 2x -10)
T = 1000/x + 5000/( 2(x-5))
T = 1000/x + 2500 / (x-5)
