When doing consecutive numbers you have to think about how you get to the next number when counting. If I start with 5, I have to add 1 to get to 6, and add 2 to get to 7. This is the same way we do this problem except we don't know the starting number so we use x.
x + (x + 1) + (x + 2) = 117 Combine like terms
3x + 3 = 117 subtract 3 from both sides
3x = 114 divide 3 on both sides
x = 38
x + 1 = 39
x + 2 = 40
The question wants the smallest number, x = 38
I think there is a little error in your question. I guess You mean 60 vaccinations instead of 606060. I solved using 60 vaccinations.
Answer:Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.
Step-by-step explanation:
STEP 1
Let number of polio vaccines be x
and number of measles vaccine be y
such that
total does of 60 vaccinations be expressed as
x+y = 60---- equation 1
And number of doses for both vaccine to total 184 doses taken be expressed as
4x + 2y= 184 ---- equation 2
Step 2--- solving
x+y = 60---- equation 1
4x + 2y= 184 ---- equation 2
Making x the subject of formula in equation 1 and substituting it in equation 2
x= 60-y
4(60-y) +2y- 184
240-4y+2y=184
240-184= 4y-3y
56= 2y
y= 58/2 = 28
To get x , put the value of y=28 in equation 1 and solve
x+y=60
x=60-28
x=32
Therefore Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.

Answer:
6.3 years
Step-by-step explanation:
The formula for depreciation is
Where P is the initial value, A is final value, t is duration in years and r is rate in deximal point. Substituting 55, 500 for P and 20, 000 for A, 0.15 for rate, r then
Therefore, it requires about 6.3 years
