Answer:

Step-by-step explanation:

PEMDAS

P = parentheses

E = exponents

M = multiplication

D = division

A = addition

S = subtraction

If the expression contains parentheses, always solve what's in them first

then if there are exponents, solve them

then do any multiplication or division, from left to right

last, do any additon or subtraction, from left to right

In this problem all we have to do is subtract 8 and 5 to get 3 and then divide that into 54 to get 18

Use order of operations.
First step do inside the parentheses

8-5 = 3

Now you have 54 / 3

Now divide

54/3 = 18

answer: 18

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,

DIA [1.3K]

Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50

The equation model for this situation is:

$A= A_{o}(1+r)^{t}$

Using the values in above equation, we can write:

$45000000=100(1+1.5)^{t} \\ \\ 
450000=(2.5)^{t} \\ \\ 
log(450000)=log((2.5)^{t}) \\ \\ 
log(450000)=t*log(2.5) \\ \\ 
t= \frac{log(450000)}{log(2.5)} \\ \\ 
t=14.21$

This means, the person will fall sick after about 14 hours.

Helooooo?!!!!! 30 whole points

Answer:

I believe C, or the answer you have chosen, is correct.

Step-by-step explanation:

In this question, we add like, AKA similar, terms.

There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:

x^2

There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:

x^2 - x

We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:

x^2 - x + 6.

See how easy that was? :) Hope this helps you and you get a good grade on your test!!

Please rate my answer and give me Brainliest!!!!

Have an awesome rest of your day! :)
