Answer:
42x -27
Step-by-step explanation:
we apply distributive property:
7(6x – 4) + 1
7*6x - 7*4 +1
42x - 28 +1
42x -27
After simplifying the real and imaginary parts you'd get -8i
Answer:
The answer is that both plans are equal.
Step-by-step explanation:
you start by putting the plans into an equation then you set them equal to each other. you need to assign a variable for the number of months. we'll call it M. It would look like this:
plan A - 25 + 8M
plan B - 5 + 12M
25 + 8M = 5 + 12M
Then you solve which looks like this:
25 + 8M = 5 + 12M
-8M -8M
25 = 5 + 4M
-5 -5
20 = 4M
/4 /4
5 = M
Now we aren't done after finding out what M equals. We still need to know what each plan will cost. So, we substitute what M equals into the equation. if they both end up equaling the same thing then its equal. if you get two different numbers they aren't. it would look like this:
25 + 8(5) = 5 + 12(5)
25 + 40 = 5 + 60
65 = 65
They are equal. Both plans will cost 65 dollars.
Answer:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria in the dish is 500,000
Step-by-step explanation:
Given the information on the table
We are to follow the pattern to determine how many million bacteria were in the dish at 1 p.m. and 12 p.m.
Now:
It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:
Therefore:
- At 1pm, the number of bacteria in the dish is 1,000,000
- At 12pm, the number of bacteria is 0.5 million=0.5 X 1,000,000=500,000
