Let the number be a ....
=>Number doubled : 2a ..
=>Eight less than the no. Doubled : 2a - 8
=>Eight less than the no. doubled is 20 more than the no. : 2a - 8 = 20 + a
=>2a - 8 - 20 - a = 0
=>2a -a - 20 -8 = 0
=>a -28 = 0
=>a = 28
=>so the number is 28...
Hope it helps!!!

Answer:
37.67%
Step-by-step explanation:
Suppose initially a price of $ 100
Increasing per month at a rate of 2.7%. Which is equal to 0.027
Now applying the formula:
Vf = Vi * (1 + m) ^ n
where Vf is the final quantity, Vi is the initial value, m is the rate and n is the number of months.
We know that 1 year, is 12 months, since the rate is monthly means, n = 12, we replace:
Vf = 100 * (1 + 0.027) ^ 12
Vf = 137.67
It means price increase in 1 year = 137.67 - 100 = 37.67
Which means that n a year increases to 37.67%
1. Distribute 6: 5+6w+48=59
2. Add like terms: 6w+53=59
3. Subtract 53 on both sides: 6w=6
4. Dived by 6 on both sides: w=6
Answer: w=6
