Answer:

Last year Dr. Potter give<u> 32 </u>Polio vaccination and <u>28</u> measles vaccination.

Step-by-step explanation:

Given:

Each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.

Last year ,Dr. Potter gave a total of 60 vaccinations that consisted of a total of 184 doses.

Now, to find the number of polio vaccinations and many measles vaccination.

Let the number of Polio vaccination be x.

And let the number of measles vaccination be y.

So, the total number of vaccinations:

x+y=60

y=60-x .......(1)

<em>As, given each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.</em>

Thus, the total number of doses:

4x+2y=184

Substituting the value of y from equation (1):

4x+2(60-x)=184

4x+120-2x=184

2x+120=184

<em>Subtracting both sides by 120 we get:</em>

2x=64

<em>Dividing both sides by 2 we get:</em>

x=32.

<em>The number of Polio vaccination = 32.</em>

Now, putting the value of x in equation (1):

y=60-x

y=60-32

y=28.

<em>The number of measles vaccination = 28.</em>

Therefore, last year Dr. Potter give 32 Polio vaccination and 28 measles vaccination.

Select the function that represents the simple interest formula.
Anit [1.1K]

Answer:

D. A(n) = P + (n-1)i*P

Step-by-step explanation:

The formula to calculate the simple interest is:

SI = \frac{Pnr}{100}

Replace i by \frac{r}{100}, then

SI = Pni

where n is the number of years.

So, for n-1 years, the simple interest is:

SI = P(n-1)*i

The Total amount is:

A(n) = P + (n-1)i*P

Solve the equation m=2n-p
allsm [11]

Here is your answer:


Move all terms with m to the left, all other terms to the right:


m + 2n + -2n = -2n + p

Combine like terms:

2n + -2n = 0

m + 0 = -2n + p

Which would equal "m = -2n + p" after you simplify.


Hope this helps!
