Answer:
6/8 and 9/12
Step-by-step explanation:
You can find any by multiplying numerator and denominator by any given number. The number multiplied has to be the same for the top and the bottom
1. Number is 2
3/4 * 2/2 = 6/8 (3*2 = 6 and 4*2 = 8)
2. Number is 3
3/4*3/3 = 9/12 (3*3 = 9 and 3*4 = 12)
First multiply the parenthesis:
20 - b = 1/3b + 16/3
Then combine like terms:
20 -b + b = 1/3b + b + 16/3
20 - 16/3 = 1/3b + b + 16/3 -16/3
20 - 16/3 = 1/3b + b
44/3 = 4/3b
and if your looking for b;
44/3 (divided by) 4/3 = b
11 = b...is your final answer!

Answer:
After 2.80 years the price drops to 300 $
Step-by-step explanation:
Ryan bought a new computer for $2,100.
Price of computer = 2100 $
The value of the computer decreases by 50% each year.
Let p(n) be the price of computer after n years.

Now we need to find n when price is 300 $.
0.50ⁿ x 2100 = 300
0.50ⁿ = 0.143
n log (0.5) = log 0.143
n x -0.301 = -0.845
n = 2.80
After 2.80 years the price drops to 300 $
