First you need to get rid of the parenthesis by distributing the 0.6 to each term inside.
(0.6)(10n) + (0.6)(25) =10+5n
6n +15 = 10+5n subtract the 5n on both sides and subtract 15 from both sides
6n-5n = 10-15
n=-5
Answer:the first ans (f(x)=(1/x+2)+3
Step-by-step explanation:
Answer:
The answer is 7 2/3 cans for the next 6 days.
Step-by-step explanation:
Given: The dog ate 50 cans in 30 days.
To get how many cans per day, divide:
50/30 = 1 2/3 cans per day.
To get how many cans for 6 days, multiply:
6 * 1 2/3 = 18/3 + 5/3 = 23/3 = 7 2/3 cans or 7.667 in decimal form.
Hope this helps!! Have an Awesome day!!! :-)
Answer: The total number of logs in the pile is 6.
Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.
We are to find the total number of logs in the pile.
Let n represents the total number of logs in the pile.
Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with
first term, a = 32 and common difference, d = -6.
We know that
the n-th term of an arithmetic sequence with first term a and common difference d is

Since there are n logs in the pile, so we get

Thus, the total number of logs in the pile is 6.
f(2) This means that x is 2, so you plug in 2 for x in the equation




Your answer is D
