El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.

Step-by-step explanation:

- First, the data must be taken into account to create the equations:

- Where:

 X = Number of polio vaccines and Y = Number of measles vaccines.

Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.

- We clear the variable that we want to find in each equation:

- Now both equations are equalized in terms of the same variable:

- Then X is cleared to find its value:

- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values of Y

- Finally, both values are used to see if equation 2 gives us the correct data:

- The answer is given:

Dr. Potter gave 32 polio and 28 measles vaccines.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.

step-by-step explanation:

can i have brainliest

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
