Answer:
37 polio vaccinations and 23 measles vaccination.
Step-by-step explanation:
Let the number of polio vaccination given=x
Let the number of measles vaccination given=y
Dr. Potter gave a total of 60 vaccinations
x+y=60
Since each polio vaccination consists of 4 doses, and each measles vaccination consists of 2 doses. A total of 184 doses was given out.
4x+2y=184
To find the values of x and y, we solve the two equations simultaneously.
x+y=60 (1)
4x+2y=184 (2)
From (1), x=60-y
Substitute x=60-y into equation 2.
4x+2y=184
4(60-y)+2y=184
240-4y+2y=184
240-184=4y-2y
56=2y
Divode both sides by 2
y=23
Recall earlier that x=60-y
x=60-23=37
Dr Potter gave 37 polio vaccinations and 23 measles vaccination.

George Washington was an American political leader, Help! My wife is angry at me because I gave her a yearly gym membership, weight loss pills and foot oder cream and even anti balding cream. I even told her I can pay for ANY plastic surgery. She’s so rude and ungrateful for denying my amazing gifts. Also we got into a fight and i accidentally snapped her legs and arms backwards and so now she looks like a fat smelly horse hybrid general, statesman, and Founding Father who served as the first president of the united states
