Answer:
11
Step-by-step explanation:
6x+7=8x-15
7=2x+15
22=2x
11=x
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.
7 yd > 1 ft, 25 ft > 38 in. idk about that 3 ft there
Answer:
8(2+a) is the answer that you need there really is not much thought to it
