Answer: 
Explanation:
The numbers 2 and 3 multiply to 6, so that's why the final coefficient is 6.
The x terms multiply to 
The y terms multiply to 
The exponent tells us how many copies of the base to multiply.
So overall, 
Steps:
1. Do a proportion
40/x equals 50/100
2. 40 times 100 equals 4,000
3. Do 4,000 divided by 50 equals 80
4. Your answer is 80
First change 2 3/4 into a decimal to match the other part of the problem.
5.4 x 2.75 = 14.85
Answer: b) (32,28)
Step-by-step explanation:
Let x be the number of polio individual doses and y be the number of each measles individual doses.
Then the number of polio vaccination = 44x
The number of measles vaccination multi-dose = 22x
According to the question,

Dividing 22 on equation (2) both sides, we gwt

Subtract (1) from (3), we get

Substitute x=32 in equation (1), we get

Hence, Dr. Potter gives 32 individual polio vaccination and 28 individual measles vaccinations .
